Direct synthesis of N-arylamides via the coupling of aryl diazonium tetrafluoroborates and nitriles under transition-metal-free conditions

The direct synthesis of N-arylamides via the coupling of aryl diazonium tetrafluoroborates and nitriles under transition-metal-free conditions has been developed. The reported protocol is practical and represents an efficient method to produce functionalized amides in moderate to good yields.

A to aryl diazonium tetrafluoroborate salts with a nitrile preparation machine acid radical amine compounds (by machine translation)

The invention provides a high-efficiency, high-selective synthesis of different substituted functional group containing organic amide compound, it adopts the cuprous iodide as a catalyst, in order to aryl diazonium tetrafluoroborate salts compounds and organic nitrile compound as the reaction substrate, the reaction system by adding the organic solvent, water and alkali. The advantage of this method: cheap and easily obtained catalyst; the substrate has a high applicability; mild reaction conditions, safe and reliable; the resulting target product selectivity is close to 100%, yield is as high as 90% or more. The method solves the traditional synthetic organic amide compound of rigorous reaction conditions, the reaction selectivity is poor, the experimental procedure is complicated, the productivity is low and needs to be used for the environment of a harmful reagent and the like, it has good industrial application prospect. The invention also provides a corresponding different substituted functional group containing organic amide compound. (by machine translation)

Expedient synthesis of deuterium-labelled amides within micro-reactors

The pharmaceutical industry relies heavily on the synthesis of small quantities (10-500 mg) of stable, isotopically labelled compounds in the evaluation of new drug candidates for metabolism studies. As a result of the phenomenal cost of labelled materials even the preparation of small quantities can be extremely expensive. In this paper, for the first time, we report that micro-reactor technology may be used to prepare stable deuterium-labelled compounds by conducting all optimization experiments using unlabelled precursors and simply substituting the labelled derivatives once the optimization is complete. Here, we wish to present a simple, general procedure for the synthesis of amides containing isotopic labels demonstrated using [C-2H 3]acetyl chloride 1. The reaction is carried out within a micro-reactor set-up which we believe offers superiority over other reported methods viz requiring stoichiometric quantities of reagents, high containment of the system and generality of the technique, obtaining products in high yields.

Photoinduced electron transfer reactions of benzyl phenyl sulfides promoted by 9,10-dicyanoanthracene

The photoinduced oxidation of benzyl phenyl sulfides 1-3 has been investigated in MeCN using 9,10-dicyanoanthracene as sensitizer in the presence of O2. In this reaction a sulfide radical cation is formed, which undergoes one or more of the three main reaction pathways opened to these species: C-S bond cleavage, C-H bond cleavage and S-oxidation. The former route (leading to benzylic products) was observed with all the substrates investigated, whereas the second (leading to benzaldehydes) operates only with 1 and 2. Formation of sulfoxides was found solely in the photooxidation of 1. The influence of substrate structures on the relative contribution of the three pathways as well as the role of O2- in this respect are discussed.
