WebApr 2, 1998 · A new method for the preparaation of the isocyanide group is described. Treatment of alcohols with zinc reagents (ZnI 2, ZnBr 2, or ZnCl 2) and trimethylsilyl cyanide (TMSCN) in dichloromethane followed by desilylation with tetrabutylammoniium fluoride (TBAF) affords the corresponding isocyanides directly in good yields.
