The molecular structure of a 2-aryl-1,3,2-dioxaphospholane and its coordination behaviour towards platinum(II) species; molecular structures of four platinum(II) complexes

The molecular structure of the 2-aryl-1,3,2-dioxaphospholane, 2,6-(CF3)2-C6H3-P(OCH2)2 (1), has been determined by single-crystal X-ray diffraction at 120 K. Its reactions with the platinum(II) dimers trans-[PtCl(μ-Cl)(PEt3)]2, trans-[PtCl(μ-Cl)(PPh2Me)]2, trans-[PtCl(μ-Cl)(PPhMe2)]2 and trans-[PtBr(μ-Br)(PEt3)]2 have been investigated using 31P NMR solution-state spectroscopy. Monomeric trans- and cis-Pt(II) complexes were formed; the molecular structures of cis-[PtCl2(L)(PR2R′)] (RR′Et (3), RPh, R′Me (7)), cis-[PtBr2L(PEt3)] (9) and cis-[PtCl2L2] (10), where L = 2,6-(CF3)2-C6H3-P(OCH2)2, have been ascertained at 120 K.
