Synthesis of heteropnictogen ligands via PI transfer†
Abstract
The heterodipnictogen complexes [{CpMo(CO)2}2(μ,η2:2-PE)] (E = P, As, Sb) react with the phosphorus(I) transfer reagent [(BZIMPY)P][CF3SO3] (BZIMPY = 2,6-bis(benzimidazole-2-yl)pyridine) in a transmetallation reaction forming the unprecedented [CpMo(CO)2(η3-P2E)] complexes.
