An efficient method for the preparation of styrene derivatives via Rh(III)-catalyzed direct C-H vinylation

, p. 1332 - 1335 (2015)
The development of a method for the Rh(III)-catalyzed direct vinylation of an aromatic C-H bond to give functionalized styrenes in good yield, using vinyl acetate as a convenient and inexpensive vinyl source, is reported. High functional group tolerance is demonstrated for electronically distinct arenes as well as different directing groups. Mechanistic investigation resulted in the characterization of a novel rhodium-metallacycle, which represents the first X-ray structure of a [1,2]-Rh(III)-alkenyl addition adduct.

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.

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.
