Wu, Ao-rong published the artcileSynthesis of aromatic acyl cyanides catalyzed by Sm(OTf)3, COA of Formula: C8H6ClN, the publication is Nongyao (2013), 52(4), 241-243, 246, database is CAplus.
The paper aimed to study a new synthetic method of aromatic acyl cyanides. Catalyzed by samarium triflate [Sm(OTf)3] aromatic acyl chlorides was reacted with sodium cyanide to give aromatic acyl cyanides. Under the optimal reaction conditions, the yields and purities of aromatic acyl products reached about 90% and above 98% resp. It was a novel practical method to prepare aromatic acyl cyanides, with mild reaction conditions and high selectivity, and without the use of phase transfer catalyst.
