Palladium-catalyzed carbonylative synthesis of alkynones from aryl iodides and phenylpropiolic acid employing formic acid as the CO source
Li, Chong-Liang,Zhang, Wan-Quan,Qi, Xinxin,Peng, Jin-Bao,Wu, Xiao-Feng
, p. 9 - 11 (2017)
A palladium-catalyzed procedure for the decarboxylative-carbonylation of phenylpropiolic acid with iodobenzenes to the corresponding alkynones with formic acid as carbon monoxide source has been developed. Various alkynones were produced in moderate to good yields.
