Convenient preparation of (η4-alkadiene)dichloroplatinum(II) complexes from [PtCl6]2− anions and their reduction to platinum(0) alkene complexes under phase-transfer catalysis conditions
چکیده انگلیسی

Convenient one-pot reduction-complexation reactions of hexachloroplatinato(IV) anions to (η4-alkadiene)dichloroplatinum(II) complexes (η4-alkadiene = COD, DAE, DCPD, NBD) under suitable phase-transfer catalysis conditions are reported. Reduction to zerovalent platinum alkene complexes has been obtained in the presence of an excess of alkene, potassium formate and 18-crown-6 as phase-transfer catalyst (alkene = COD, NB, dba). The crystal and molecular structure of [Pt1.03(dba)3]·CH2Cl2 has been studied by X-ray diffraction methods: it can be described as a solid solution of Pt(dba)3 and Pt2(dba)3, the mononuclear complex being largely prevailing.

Convenient one-pot reduction-complexation reactions of hexachloroplatinato(IV) anions to (η4-alkadiene)dichloroplatinum(II) complexes and further reduction to zerovalent platinum alkene complexes under phase transfer catalysis conditions are described. The crystal and molecular structure of [Pt1.03(dba)3]·CH2Cl2 is reported.Figure optionsDownload as PowerPoint slideHighlights
