A highly basicphosphine, tris(2,4,6-trimethoxy phenyl)phosphine (TTMPP), catalyzes cyanomethylation using trimethylsilylacetonitrile (TMSCH2CN) to give the corresponding products in good to high yields, with both carbonyl compounds and imines.
Catalytic cyanomethylation of various carbonyl compounds with (trimethylsilyl)acetonitrile (TMSCH2CN) in the presence of Lewis bases such as cesium or lithium acetate proceeded smoothly to afford t...
An aldol-type reaction of organonitriles with aldehydes was catalyzed by a RhI(OR) species underambientconditions, and the reaction displayed a broad substrate scope with respect to both organonitrile and aldehyde components.

room temperature coupling of aldehydes with acetonitrile under base‐free conditions. The catalytic system is long‐lived and remarkably efficient with high turnover numbers (TONs) and turnover frequencies (TOFs) achieved. The mild reaction conditions allow a wide variety of aldehydes, including base‐sensitive ones, to catalytically react with acetonitrile.
