On the Preparation of Acyl Cyanides from Aldehydes
Haerle, Helmut,Jochims, Johannes C.
, p. 1400 - 1412 (2007/10/02)
The O-silylated cyanohydrins 3 prepared from the aldehydes 1 with trimethylsilyl cyanide are oxidized photochemically or thermally with N-bromosuccinimide to afford the acyl cyanides 4a-n.Scope and limitations of the procedure are discussed.
