摘要：

The structures of five stabilized phosphonium ylides 1-5 were studied by H-1, C-13, and P-31 NMR. Various trapping experiments were followed by investigation of the relative reactivities of these ylides vis-a-vis benzaldehyde. A novel effect of some significance, the influence of acidic contaminants (conjugate acids, H2O, etc.) on the structure and reactivity of these compounds, is discussed.
