- 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.

- Amidation of Aldehydes with Amines under Mild Conditions Using Metal-Organic Framework Derived NiO@Ni Mott-Schottky Catalyst
-
Here we report a facile method for the synthesis of nickel oxide-nickel (NiO@Ni) Mott-Schottky catalyst employing metal-organic framework (MOF) as the precursor. A direct amidation protocol of aldehydes with amines has been optimized under mild conditions using NiO@Ni Mott-Schottky catalyst and it shows far better catalytic activity than the NiO?Ni nanoparticles prepared from simple Ni2+ salt under similar reaction conditions. The heterogeneous catalyst is robust, recyclable and efficient to provide comparable yield to costly ligand-based homogeneous Ni catalysts. The scope of the reaction protocol has been explored with variably substituted substrates. The reaction initiates by homolytic cleavage of peroxide and proceeds through radical mechanism.

- Copper-Catalyzed Aerobic Oxidative Amidation of Benzyl Alcohols
-
A Cu-catalyzed synthesis of amides from alcohols and secondary amines using the oxygen in air as the terminal oxidant has been developed. The methodology is operationally simple requiring no high pressure equipment or handling of pure oxygen. The commercially available, nonprecious metal catalyst, Cu(phen)Cl2, in conjunction with di-tert-butyl hydrazine dicarboxylate and an inorganic base provides a variety of benzamides in moderate to excellent yields. The pKa of amine conjugate acid and electronics of alcohol were shown to impact the selection of base for optimal reactivity. A mechanism consistent with the observed reactivity trends, KIE, and Hammett study is proposed.
