Acylation of phosphoranes with alkyl chloroglyoxylates does not appear to have been reported before. Although we have demonstrated such an acylation with only two phosphoranes (2 and ethyl triphenylphosphoranylideneacetate), it probably is a generally applicable reaction. The phosphoranes 1, 4, and 5 are" resonance-stabilized" ylides2 and thus are stable to oxygen and water at room temperature; 1 could not be alkylated with ...
