METHODS OF CONTROLLING CROP PESTS USING AROMATIC AMIDE INSECT REPELLENTS, METHODS OF MAKING AROMATIC AMIDE INSECT REPELLENTS, AND NOVEL AROMATIC AMIDE INSECT REPELLENTS

Methods of protecting fruit crops from flying insect pests and of repelling flying insects using aromatic amide compounds are disclosed. The methods apply the compounds to various surfaces, such as the fruit crops, the ground or structures adjacent to the fruit crops, or an object, article, human skin or animal. The compounds have the formula RxC6Hy—C(═O)—N(Cy), where RxC6Hy is a substituted phenyl group, each R group is independently C1-C6 alkyl, substituted C1-C4 alkyl, (substituted) C6-C10 aryl, C1-C4 alkoxy, C6-C10 aryloxy, halogen, nitro, cyano, cyanate, isocyanate, nitroso, C1-C4 alkylthio, phenylthio, (halogen-substituted) C1-C4 alkylsulfonyl, phenylsulfonyl, tolylsulfonyl, amino, mono- or di-C1-C4 alkylamino, diphenylamino, di-C1-C4 alkylamido, formyl, C2-C7 acyl, or C1-C6 alkoxycarbonyl; x is an integer of 1 to 5; x+y=5; Cy is a C2-C8 (substituted) alkadiyl, a C4-C6 (substituted) alkenediyl, or a (substituted) diyl of the formula —(CH2CH2)—O—(CH2CH2)—, —(CH2CH2)—NR′—(CH2CH2)— or —(CH2CH2)—S—(CH2CH2)— that, along with the amide N atom, forms a non-aromatic cyclic group; and R′ is C1-C6 alkyl, substituted C1-C4 alkyl, (substituted) C6-C10 aryl, or (substituted) benzyl.

Direct Synthesis of Enamides via Electrophilic Activation of Amides

A novel, one-step N-dehydrogenation of amides to enamides is reported. This reaction employs the unlikely combination of LiHMDS and triflic anhydride, which serves as both the electrophilic activator and the oxidant, and is characterized by its simple setup and broad substrate scope. The synthetic utility of the formed enamides was readily demonstrated in a range of downstream transformations.

Cobalt-catalyzed aminocarbonylation of (hetero)aryl halides promoted by visible light

The catalytic aminocarbonylation of (hetero)aryl halides is widely applied in the synthesis of amides but relies heavily on the use of precious metal catalysis. Herein, we report an aminocarbonylation of (hetero)aryl halides using a simple cobalt catalyst under visible light irradiation. The reaction extends to the use of (hetero)aryl chlorides and is successful with a broad range of amine nucleophiles. Mechanistic investigations are consistent with a reaction proceeding via intermolecular charge transfer involving a donor-acceptor complex of the substrate and cobaltate catalyst.

Cross-Dehydrogenating Coupling of Aldehydes with Amines/R-OTBS Ethers by Visible-Light Photoredox Catalysis: Synthesis of Amides, Esters, and Ureas

A straightforward synthesis of amides, ureas, and esters is reported by visible-light cross-dehydrogenating coupling (CDC) of aldehydes (or amine carbaldehydes) and amines/R-OTBS ethers by photoredox catalysis. The reaction is found to be general and high yielding. A plausible mechanistic pathway has been proposed for these transformations and is supported by appropriate controlled experiments.

AMIDATION METHOD AND ESTERIFICATION METHOD USING SULFONIC ACID HALIDE

PROBLEM TO BE SOLVED: To provide a safe and economical method for rapidly synthesizing amides and esters in high yield. SOLUTION: There is provided a method for amidating an amine or a derivative thereof using a sulfonic acid halide, where a sulfonic acid halide is allowed to act as an activator on a carboxylic acid or a derivative thereof to synthesize an active ester, and the active ester is reacted with an amine or a derivative thereof as a nucleophile to amidate the amine or the derivative thereof to obtain a corresponding amide or a derivative thereof. In a similar manner, a sulfonic acid halide is allowed to act as an activator on a carboxylic acid or a derivative thereof to synthesize an active ester, and the active ester is reacted with an alcohol or a derivative thereof as a nucleophile to esterify the alcohol or the derivative thereof to obtain a corresponding ester or a derivative thereof.

Catalytic bio-chemo and bio-bio tandem oxidation reactions for amide and carboxylic acid synthesis

A catalytic toolbox for three different water-based one-pot cascades to convert aryl alcohols to amides and acids and cyclic amines to lactams, involving combination of oxidative enzymes (monoamine oxidase, xanthine dehydrogenase, galactose oxidase and laccase) and chemical oxidants (TBHP or CuI(cat)/H2O2) at mild temperatures, is presented. Mutually compatible conditions were found to afford products in good to excellent yields. This journal is

Preparation of tertiary amides via aryl, heteroaryl, and benzyl organozinc reagents; Scope and limitations

A facile synthetic protocol for the preparation of tertiary amides has been developed. The title compounds have been successfully obtained by the Pd-catalyzed cross-coupling reactions of readily available aryl and benzyl organozinc reagents with the appropriate carbamoyl chlorides.

Aminolysis of Y-substituted-phenyl 2-methoxybenzoates in acetonitrile: Effect of the o-methoxy group on reactivity and reaction mechanism

Second-order rate constants (kN) were measured for aminolyses of Y-substituted-phenyl 2-methoxybenzoates 2a-i and 4-nitrophenyl X-substituted-benzoates 3a-j in MeCN at 25.0 °C. The Bronsted-type plot for the reactions of 2a-i with piperidine curves downward, indicating that a change in rate-determining step (RDS) occurs. The Hammett plot for the reactions of 3a-j with piperidine consists of two intersecting straight lines, which might be taken as evidence for a change in RDS. However, the nonlinear Hammett plot has been suggested not to be due to a change in RDS but rather to the stabilization of the ground state of substrates possessing an electron-donating group (EDG) (e.g., 3a-c) through a resonance interaction, since the corresponding Yukawa-Tsuno plot exhibits an excellent linear correlation with ρ = 0.54 and r = 1.54. The ρ value found for the reactions of 3a-j in MeCN is much smaller than that reported previously for the corresponding reactions in H2O (i.e., ρ = 0.75). It is proposed that the reactions of 3a-j in MeCN proceed through a forced concerted mechanism due to instability of T± in the aprotic solvent, while the reactions of 2a-i proceed through a stepwise pathway with a stabilized T ± through an intramolecular H-bonding interaction.

The scope and limitation of nickel-catalyzed aminocarbonylation of aryl bromides from formamide derivatives

(Chemical Equation Presented) Nickel-catalyzed aminocarbonylation of aryl halides is described. A well-defined air-stable nickel-phosphite catalytic system (Ni(OAc)2 · 4H2O/phosphite 1) effectively promoted the aminocarbonylation of

Synthesis of ortho-alkoxy-aryl carboxamides via alladium-catalyzed aminocarbonylation

Various aryl carboxamides with alkoxy substituents at the ortho-position, applicable as direct intermediates toward novel ligands, were synthesised via aminocarbonylation of aryl-iodides (2-iodoanisole, 5-chloro-7-iodo-8-methoxy- quinoline, and 5-chloro-7-iodo-8-benzyloxy-quinoline) in the presence of in situ generated palladium(0) catalysts. Simple primary and secondary amines as well as aminoacid esters were used as N-nucleophiles. The optimization of the reaction conditions allowed the preferential formation of carboxamides or ketocarboxamides by simple or double carbon monoxide insertion, respectively. A strong dependence of the chemoselectivity on carbon monoxide pressure was observed. Copyright Taylor & Francis Group, LLC.
