Paragraph 0017-0020; 0100-0103, (2017/02/28)
The invention discloses a one-step synthetic method of meta-substituted N-arylbenzamide compounds. Transition metal ruthenium is used as a catalyst, and the meta-substituted N-arylbenzamide compounds are synthesized in one step through carboxy-based o-C-H functionalization/ decarboxylation coupling reaction of aromatic acid and phenyl isocyanate compounds. The method has the advantages that the raw materials are simple and readily available, the catalyst is cheap, the reaction operation is simple, the utilization rate of atoms is high, the method is environment-friendly and the like.

A binaphthyl-supported Pd nanoparticles (Pd-BNP)-catalyzed aminocarbonylation of aryl iodides in the presence of carbon monoxide and amines for the synthesis of amides has been developed. This methodology provides an efficient route for the synthesis of a COX-2 enzyme inhibitor having anti-inflammatory activity.

Carboxylate as a promising and valuable directing group has attracted a great deal of attention. However, employing it as a traceless direction group has rarely been reported. We developed the ruthenium-catalyzed amidation of substituted benzoic acids wit

The rate of the reactions of aroyl chlorides with primary arylamines in 3.5, 5, and 7M solutions of tert-butyl alcohol in chlorobenzene at 25 deg C was measured.The effect of the structure of the reagents on the process rate was determined quantitatively by means of the Hammett-Taft and crossed correlation equations.The isoparametric points with respect to the structure of the substrate and the nucleophile were reached experimentally, and the transition through some of these points was also realised.It was found that the specific solvation of the primary arylamines by the tert-butyl alcohol was nonuniform in that an incre ase in the concentration of the alcohol in the investigated range reduced, did not change, and increased the rates of the reactions with 3-chloroaniline, 3-nitroaniline, and 3-nitro-5-methoxycarbonylaniline respectively.The effect of specific solvation on the behavior of the correlation parameters is discussed.

Rates were measured for the reactions of aroyl bromides with primary arylamines in 1:1 chlorobenzene-cyclohexane at 25 deg C.The kinetic data were treated by the Hammett-Taft equations and cross correlation.This is the first reported transition through an isoparametric point relative to the structure of the nucleophile accompanied by inversion of the sign of the sensitivity parameter relative to the substrate structure in the aroyl bromide-primary arylamine reaction system.The results of the cross correlation analysis were interpreted on the basis of a concerted mechanism involving nucleophilic substitution at the carbonyl carbon atom.The relationship between the reactivity of the system studied and its selectivity was examined.
