Preparation and Characterization of P2BCh Ring Systems (Ch=S, Se) and Their Reactivity with N-Heterocyclic Carbenes
Abstract
Four-membered rings with a P2BCh core (Ch = S, Se)
have been synthesized via reaction of phosphinidene chalcogenide
(Ar*P=Ch) and phosphaborene (Mes*P=BNR2). The mechanistic
pathways towards these rings are explained by detailed
computational work that confirmed the preference for the formation
of P–P, not P–B, bonded systems, which seems counterintuitive
given that both phosphorus atoms contain bulky ligands. The
reactivity of the newly synthesized heterocycles, as well as that of
the known (RPCh)n rings (n = 2, 3), was probed by the addition of Nheterocyclic
carbenes, which revealed that all investigated
compounds can act as sources of low-coordinate phosphorus
species.
