Practical synthesis of ferrocenyldiarylstibines and bismuthines
Abstract
The reaction of in situ-generated lithioferrocene with pnictines EAr3 (E = Sb and Bi, Ar = aryl) is presented as a reliable, robust, and practical approach for synthesising ferrocenyldiarylstibines and bismuthines. In addition to simple derivatives FcEAr2 (Fc = ferrocenyl), the method enables the preparation of functional derivatives, thereby opening access to P,Sb and P,Bi-hybrids.
