The products of the photolysis of a number of platinacyclopentanes is solution at 25 deg C under a variety of conditions have been determined.With (L = PMe2Ph, PPh3) in CH2Cl2, CH2Br2 and (CH3)2SO the hydrocarbon products are exclusively ethylene and but-1-ene.Formation of the latter through a 1,3-hydrogen shift is preceded by phosphine ligand dissociation.The photolysis of gave methane, ethylene, but-1-ene and n-pentane together with a little n-butane, the methane being formed from internal hydrogen abstraction by the CH3 group in the excited reactant molecule.Photodecomposition of the platinum(II) compounds (L = (PMe2Ph)2, (PPh3)2, Ph2PCH2CH2PPh2) gave ethylene, but-1-ene, pent-1-ene (with the halogenated solvents) and with some systems appreciable yields of n-butane, the latter being the result of internal abstraction of two hydrogen atoms by the C4H8 moiety.The formation of pentene is probably preceeded by the addition of CH2Cl2 or CH2Br2 to the excited reactant molecule.Addition of diphenylphosphine promotes the production of n-butane.

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

[PPh4]2[M(C2N2 S2)2] (M = Pt, Pd) and [Pt(C2N2S2) (PR3)2] (PR3 = PMe2Ph, PPh3) and [Pt(C2N2S2)(PP)] (PP = dppe, dppm, dppf) were all obtained by the reaction of the appropriate metal halide containing complex with potassium cyanodithioimidocarbonate. The dimeric cyanodithioimidocarbonate complexes [{Pt(C2N2S2) (PR3)}2] (PR3 = PMe2Ph), [M{(C2N2 S2)(η5-C5Me5)}2] (M = Rh, Ir) and [{Ru(C2N2S2) (η6-p-MeC6H41Pr)}2] have been synthesised from the appropriate transition metal dimer starting material. The cyanodithioimidocarbonate ligand is S,S and bidentate in the monomeric complexes with the terminal CN group being approximately coplanar with the CS2 group and trigonal at nitrogen thus reducing the planar symmetry of the ligand. In the dimeric compound one of the sulfur atoms bridges two metal atoms with the core exhibiting a cubane-like geometry.
