ChemInform Abstract: Intramolecular (4 + 2) Diels-Alder Cycloaddition Reactions of Phospholes with Vinylphosphines Promoted by Palladium and Platinum

Reactions of (vinylphosphine) 2 MX 2 complexes with (1-R-3,4-dimethylphosphole) 2 MX 2 complexes (where vinylphosphine=Ph 2 VyP, PhVy 2 P, Et 2 VyP; R=Ph, Bzl, t-Bu; X=Cl, Br, I; M=Pd, Pt) produce dihalo [2-(R',R″-phosphino)-5,6-dimethyl-7-R-7-phosphabicyclo [2.2.1] hept-5-ene] metal(II) complexes via an intramolecular Diels-Alder [4+2] cycloaddition
