off-white to light yellow crystalline powder | [Uses]
(Triphenylphosphoran?ylidene)?acetonitrile is a reactant in the synthesis of largazole analogues which displays potent cell growth inhibition and cytotoxicity. As well, is used in the synthesis of monoterpene derivatives against leukemia. | [Acquired resistance]
(Triphenylphosphoranylidene)acetonitrile may be generated by deprotonation of the corresponding phosphonium salt, by cyanation of Methylenetriphenylphosphorane with p-tolyl cyanate, or by the reaction of Acrylonitrile with (Methoxycarbonylmethylene)triphenylphosphorane.
