Cross-coupling reactions of chloroformates with organocopper reagents, derived from Grignardreagents, cuprous bromide and lithium bromide, provide a rapid and straightforward method for the synthesis of esters.

cyclometalated C,N-chelate half-sandwich ruthenium complexes based on N-heterocyclic ligands were prepared through a simple route with good yields. These air- and moisture-stable cyclometalated ruthenium complexes showed excellent catalytic efficiency in phenoxy carbonylation of arylhalides with phenyl formate derivatives as a CO source and phenol as a coupling partner under air. Ester products were

palladium-catalyzed carbonylation of aryl, alkenyl, and allyl halides with phenyl formate is reported. This procedure does not use carbon monoxide and affords one-carbon-elongated carboxylic acid phenyl esters in excellent yields. The reaction proceeds smoothly under mild conditions and tolerates a wide range of functional groups including aldehyde, ether, ketone, ester, and cyano groups. Furthermore, a variety
