Twenty-five imidoyl triphenylphosphonium methylides III were prepared from triphenylphosphonium methylide and imidoyl chlorides or imidates in moderate yields. The configration of these ylides was assigned on the basis of NMR spectroscopic studies. N-Tosyl substituted ylides showed no reactivity toward aldehydes, whereas N-aryl substituted ylides could be converted easily into α,β-unsaturated ketimines in good yields. The reaction of III with carbon disulfide was also studied.
