Article abstract of DOI:10.1055/s-1992-26115

Several [1-(2-hydroxybenzoyl)alkylidene]triphenylphosphoranes have been obtained in good yields through acylation of the corresponding alkylidenetriphenylphosphoranes, prepared in situ, by the easily available methyl 2-hydroxybenzoates. These ylides prove
