An effective borate-mediated approach to 1-trifluoromethyl-1-hydroxy-3- ketophosphonates, phosphinates, and phosphine oxides
Ethyl 1-trifluoromethyl-1-hydroxy-3-oxo-phosphonates, the related (methyl)phosphinates and (phenyl)phosphinates, and phosphine oxides were obtained in good yield via direct phosphonylation of acyltrifluoroacetones with diethyl phosphite, ethyl (methyl)pho
