WebOct 12, 2024 · This work reports a green method for the synthesis of aryl selenocyanates via a three-component reaction of arylboronic acids, Se powder, and trimethylsilyl cyanide (TMSCN) under metal-free and additive-free conditions. Remarkably, TMSCN acts as not only the substrate, but also the catalyst. WebNov 1, 2003 · During attempts to prepare arylpalladium(II) cyano complexes we discovered that trans-bromo[4-(trifluoromethyl)phenyl]bis(triphenylphosphine)palladium(II) (1) [12] (Fig. 1) reacts readily and highly selectively with TMSCN.The corresponding benzonitrile was obtained in 95% yield even below 0 °C (Scheme 3).Hence, we thought that TMSCN should …

WebBase-catalyzed/mediated nucleophilic additions of TMSCN to α- (trifluoromethyl)styrenes and 2-trifluoromethyl enynes proceeded smoothly at room temperature under mild and transition-metal-free conditions without affecting the trifluoromethyl group to afford the corresponding CF 3 -containing alkyl, alkynyl, and butadienyl nitriles in good yields … Trimethylsilyl cyanide is the chemical compound with the formula (CH3)3SiCN. This volatile liquid consists of a cyanide group, that is CN, attached to a trimethylsilyl group. The molecule is used in organic synthesis as the equivalent of hydrogen cyanide. It is prepared by the reaction of lithium cyanide and trimethylsilyl chloride: LiCN + (CH3)3SiCl → (CH3)3SiCN + LiCl dick martin love boat
