Conversions of aryl carboxylic acids into aryl nitriles using multiple types of Cu-mediated decarboxylative cyanation under aerobic conditions

Here, we used malononitrile or AMBN as a cyanating agent to develop efficient and practical protocols for Cu-mediated decarboxylative cyanations, under aerobic conditions, of aryl carboxylic acids bearing nitro and methoxyl substituents at the ortho position as well as of heteroaromatic carboxylic acids. These protocols involved economical methods to synthesize value-added aryl nitriles from simple and inexpensive raw materials. Further diversification of the 2-nitrobenzonitrile product was performed to highlight the practicality of the protocols. This journal is

A preparation method for 4-methoxy-2-nitrobenzoic acid

An industrial preparation method for 4-methoxy-2-nitrobenzoic acid is disclosed. In the method, p-difluorobenzene is adopted as an initial raw material and subjected to nitration, ammonolysis, diazotization bromination, cyaniding, methoxylation and hydrolysis which are six steps to synthesize the 4-methoxy-2-nitrobenzoic acid. The 4-methoxy-2-nitrobenzoic acid obtained by the method is white powdered solid with purity being 98.5%, the raw material conversion ratio in each step is 100%, and the total yield of the whole process is 35.8%.

Tetramethylammonium chloride as a selective and robust phase transfer catalyst in a solid-liquid halex reaction: The role of water

Tetramethylammonium chloride (TMAC) is an effective phase transfer catalyst for the selective chloride/fluoride exchange reaction of activated aryl chlorides with potassium fluoride provided that the amount of water in the system is limited and controlled.
