title = "Pt(ii)-Chiral diene-catalyzed enantioselective formal [4 + 2] cycloaddition initiated by C-C bond cleavage and elucidation of a Pt(ii)/(iv) cycle by DFT calculations",
abstract = "A chiral Pt(ii) complex was readily prepared from [PtCl2(C2H4)]2 and Hayashi's diene. Its dicationic derivative efficiently catalyzed a formal intramolecular [4 + 2] cycloaddition of biphenylenes possessing substituted arylalkynes tethered by an ortho-phenylene moiety at ambient temperature and axially chiral cycloadducts were obtained in excellent yields and ees. A study of the DFT calculations revealed a Pt(ii)/(iv) cycle including oxidative addition of biphenylene along with C-C bond cleavage. This journal is ",
