Metal-free access of bulky N,N′-diarylcarbodiimides and their reduction: bulky N,N′-diarylformamidines

Abstract

A facile synthetic protocol for the preparation of <italic>N</italic>,<italic>N</italic>′-diarylcarbodiimides and their reduction with sodium borohydride in ethanol to obtain <italic>N</italic>,<italic>N</italic>′-diarylformamidines has been demonstrated.
