摘要：

The stabilized anion {[Ph2P(S)]2CH}- with lithium as counter cation 1a reacts with formaldehyde or benzaldehyde to give vinylidene phosphine sulfides [Ph2P(S)]2C = CHR, where R is H or Ph, respectively(3, 4). The same anion with potassium as counter cation 1b gives vinyl phosphine sulfides (9-11). The formation of these two different classes of compounds is dependent on the cation and the solvent used. The vinylidene phosphine sulfides can be reduced cleanly to produce the corresponding vinylidene tertiary phosphines 6 and 7.
