Aryl imines formed from aldehydes and amines undergo smoothly in situ nucleophilic addition with trimethylsilyl cyanide (TMSCN) in the presence of catalytic amount of hydrated rhodium(III) iodide to afford the corresponding α-aminonitriles in excellent yield. The low catalytic loading (2 mol %), mild experimental conditions, and short reaction time (mostly within 13 min) represent the key features

reaction is used in the synthesis of unsymmetrical vicinal diamines via the one-pot synthesis of α-cyanoamines. This methodology is further applied to the efficient synthesis of imidazolidinones. An easy-to-use bis(amidate)titanium precatalyst permits efficient approaches to heterocyclic chemistry from terminal alkynes. hydroamination - titanium - amines - heterocycles - tandem reactions

The multicomponent Strecker reactionusing trimethylsilyl cyanide was accomplished without any type of Lewis acid. The reaction performed in acetonitrile as solvent gave excellent results for any class of aldehydes (aromatic or aliphatic), as well as amines (aromatic or aliphatic). In many cases, α-aminonitrile product was isolated pure after the usual work-up, with quantitative chemical yields. A
