Abstract

Isocyanides undergo a facile insertion into activated X-H bonds. Missing from these heteroatom reactions is the insertion of isocyanides into amines promoted by non-metal activators. Described in this thesis is the first insertion of isocyanides into primary and secondary amines using silicon tetrachloride as a non-metal activator to generate formamidines, a valuable functionality for synthesizing pharmaceuticals. In addition, formamidines are widely used as insecticides and acaricides and have been reported to improve the performance of solar cells. The research described in this thesis will describe the development of a new method to make formamidines, the likely reaction mechanism, the reaction scope, and their isolation, characterization, and stability.
