Recent Literature

A facile synthesis of aryl carboxylic acids from aryl ketones by aerobic photooxidation using the inexpensive and easily handled CBr4 as catalyst is applicable to inert compounds under usual photo-irradiation conditions, and appears very attractive for the expansion of the Norrish Type I reaction.

The presence of catalytic amounts of carbon tetrabromide enables an aerobic photooxidative cleavage of carbon-carbon triple bonds to carboxylic acids under photoirradiation.

A base-promoted dibromination of enamides using CBr4 as a bromine source provides β,β-dibrominated secondary enamides. These novel products can be readily transformed to 5-Br oxazoles via Cu(I) catalyzed intramolecular cyclization in good yields.

A carbon tetrabromide mediated oxidative carbon-nitrogen bond formation of 2-aminopyridines or 2-aminopyrimidines with β-keto esters or 1,3-diones provides substituted imidazo[1,2-α]pyridines or imidazo[1,2-α]pyrimidines under mild and metal-free conditions.
