Copper mediated decarboxylative direct C–H arylation of 5-membered heteroarenes with aryl carboxylic acids is developed using the molecular oxygen as sole oxidant. Copper plays the dual role in decarboxylation and C–H arylation.

Carboxylic acids are exhaustively C-methylated to t-butyl compounds by excess trimethylaluminium at c. 120�. Benzoic acid for example, gives t-butylbenzene. Similarly methylated are o-fluoro-, o-bromo-, and m-chloro-benzoic acids, 5-chloro-3-phenylsalicylic acid, 1-naphthoic acid, palmitic, oleic and undec-10-enoic acids. Adamantane-1-carboxylic acid gives mostly l-isopropenyladaman- tane, along with some 1-t-butyladamantane. Cinnamic acid gives mainly the allylically rearranged 2-methyl-4-phenylpent-2-ene. Triphenylacetic acid behaves atypically; 1,1,1-triphenylpropan-2-one and 3,3,3-triphenylpropyne result.
