The synthesis of 2-butynenitrile (7a), 3-(4-methoxyphenyl)-(7b)-, 3-(4-ethoxyphenyl)-(7c)-, 3-(4-nitrophenyl)-(7d)- and 3-(3,4,5-trimethoxyphenyl)-(7e)-propynenitriles by thermal decomposition of the corresponding acylcyanomethylenetriphenylphosphoranes (6a-e) is described.The ethoxycarbonylcyanomethylenetriphenylphosphorane (6f) under the same conditions does not give the alkynenitrile.Cleavage to triphenylphosphine oxide and acetylenic nitrile is the predominant fragmentation observed in the mass spectra of all the ylids.
