Abstract:
Carbon-phosphorus (C-P) bond-forming reactions via homolytic aromatic substitution (HAS) of non-functionalized substrates with phosphinylidene P(O)H compounds is becoming a useful synthetic tool for the preparation of aryl and heteroaryl phosphonates, phosphinates, and phosphine oxides. This review specifically covers recent work using manganese-mediated free radical processes. Several research groups employ expensive Mn(OAc)3 , whereas our own contributions focus on the novel and inexpensive Mn(OAc)2 /MnO2 system.
