The formation of the αα-ferrocenyldicarbanion: a novel displacement of cyanide by n-butyl-lithium
Abstract
The αα-ferrocenyldicarbanion was prepared by the action of n-butyl-lithium on ferrocenylacetonitrile: when ferrocenyl-αα-dibenzylmethylcyanide was treated with n-butyl-lithium displacement of the cyanide group occurred.
