Two-step synthesis of triarylmetals (As, Sb, Bi) starting from the metal oxides and 2,6-dimethoxybenzenethiol

Reported here is a new synthetic method of triarylmetals MAr3 (M = As, Sb, Bi). It is composed of two-step reactions starting from the metal oxides: (1) A reaction of the metal oxide with 2,6-dimethoxybenzenethiol ΦSH [Φ = 2,6-(MeO)2C6H3] in the presence of acid to give the thiolatometals M(SΦ)3, and (2) A reaction of M(SΦ)3 with organolithium reagent LiAr to give MAr3 (Ar = Ph, 4-MeC6H4, 4-Me2NC6H4, Φ). Since ΦSH is odorless and crystalline, most of it can be recovered after the reactions without difficulty for repeated usages. The intermediates M(SΦ)3 are also crystalline and inert against hydrolysis.
