, p. 31688 - 31692 (2021/11/30)
The cyanosilylation was performed by using metavanadate catalysts, and in situ measurements revealed the formation of [VO2(CN)3]2- and [VO4TMS2]- under reaction conditions. The reaction of [VO2(CN)3]2-, trimethylsilyl cyanide (TMSCN), and water afforded [
Nanoceria as a recyclable catalyst/support for the cyanosilylation of ketones and alcohol oxidation in cascade
Garnes-Portolés, Francisco,Leyva-Pérez, Antonio,Rivero-Crespo, Miguel ángel
, p. 21 - 28 (2020/10/21)
The cyanosilylation of carbonyl compounds is a fundamental reaction in organic synthesis, to give cyanohydrins. Ketones are particularly reluctant to cyanosilane addition and require the action of a catalyst, and despite many soluble Br?nsted and Lewis ac
