Accessing heavy allyl-analogous [(TerN)2E]- (E = Sb, Bi) ions and their reactivity towards ECl3

Abstract

The attempted preparation of the biradicaloid [E(μ-NTer)]2 (E = Sb, Bi) yielded salts of the anion [(TerN)2E]-. These heteroatom allyl analogues could be further utilized in the reaction with pnictogen(iii) chlorides to form the first 1,3-dichloro-1-bisma-3-stiba-2,4-diazane [ClSb(μ-NTer)2BiCl].
