General description

(Tributylphosphoranylidene)acetonitrile or cyanomethylenetrimethylphosphorane (Bu3P=CHCN) is a Wittig reagent employed in the transformation of the carbonyl compounds, including aldehydes, esters, and lactones into the corresponding unsaturated nitriles.

Application

(Tributylphosphoranylidene)acetonitrile can be utilized as a reagent in the:
  • Stereoselective synthesis of skytanthine and other O- and N-containing heterocycles by Mitsunobu intramolecular cycloalkylation.
  • Wittig olefination of esters, lactones, N-Boc lactam, and cyclic imide to corresponding Wittig products.
