A platinum-cyclobutene complex: preparation and structure of bis(triphenylphosphine)-(1,2-dicyanocyclobutene)platinum(0)

Ring Expansion of a Platinacyclopropane to a Platinacyclopentane by Double Insertion of Isocyanides into Pt−C Bonds

“…Although the chemistry of the “platinacyclopropane extreme” is one of the well-investigated issues in organometallic chemistry, ,, little has been discussed on the possibility of insertion of unsaturated molecules into the Pt−C bond. Thus, the starting point of this paper is the question of whether the platinum−alkene complexes having a “platinacyclopropane extreme” structure, which is unequivocally determined, undergo the insertion of unsaturated molecules into the platinum−carbon bonds leading to the ring expansion reactions.…”
