A powerful and attractive route to develop novel photocatalysts for C-N bond formation involves the use of pyrrolidine as the substrate and cocatalyst simultaneously. Herein, a new polyoxometalate (POM)-based metal-organic framework, namely, [Ni6(OH)3(H2O

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.

The combination of conventional transition-metal-catalyzed coupling (2 e? process) and photoredox catalysis (1 e? process) has emerged as a powerful approach to catalyze difficult cross-coupling reactions under mild reaction conditions. Reported is a palladium carbodicarbene (CDC) complex that mediates both a Suzuki–Miyaura coupling and photoredox catalysis for C?N bond formation upon visible-light irradiation. These two catalytic pathways can be combined to promote both conventional transition-metal-catalyzed coupling and photoredox catalysis to mediate C?H arylation under ambient conditions with a single catalyst in an efficient one-pot process.

Rajabi, Fatemeh,Raessi, Mojdeh,Arancon, Rick A.D.,Saidi, Mohammad Reza,Luque, Rafael
, p. 122 - 126 (2015/01/09)
Co/SBA-15 nanoparticle catalysts (CoNP) were prepared using a commonly adapted synthetic route and then utilised for esterification and amidation reactions using aromatic and linear chain compounds for the production of long chain esters and amides. The study shows that the use of CoNP catalysts favours the use of aromatic reactants with electron donating substituents specifically in the para position. For the amidation reaction, good to excellent yields were obtained demonstrating tolerance towards differently substituted aromatic compounds. Overall, the synthesized catalysts proved to be efficient and highly versatile, and recyclable under the investigated conditions.
Phenazinium salt-catalyzed aerobic oxidative amidation of aromatic aldehydes
Leow, Dasheng
supporting information, p. 5812 - 5815 (2015/02/19)
Amides are prevalent in organic synthesis. Developing an efficient synthesis that avoids expensive oxidants and heating is highly desirable. Here the oxidative amidation of aromatic aldehydes is reported using an inexpensive metal-free visible light photocatalyst, phenazine ethosulfate, at low catalytic loading (1-2 mol %). The reaction proceeds at ambient temperature and uses air as the sole oxidant. The operationally easy procedure provides an economical, green, and mild alternative for the formation of amide bonds.
Metal-free one-pot oxidative amination of aldehydes to amides
Ekoue-Kovi, Kekeli,Wolf, Christian
, p. 3429 - 3432 (2008/02/12)
Metal-free oxidative amination of aromatic aldehydes in the presence of TBHP provides convenient access to amides in 85-99% under mild reaction conditions within 5 h. This method avoids free carboxylic acid intermediates and integrates aldehyde oxidation and amide bond formation, which are usually accomplished separately, into a single operation. Proline-derived amides can be prepared in excellent yields without noticeable racemization.
Trapping of translocated radicals by tetrathiafulvalene radical cation
Murphy, John A.,Roome, Stephen J.
, p. 1349 - 1358 (2007/10/02)
Aryl radicals are generated by electron transfer from tetrathiafulvalene to arenediazonium salts.The aryl radicals are translocated into alkyl radicals which undergo a C-S or C-C bond formation to tetrathiafulvalene radical cation, depending on the nucleophilicity/electrophilicity of the translocated carbon radical.
