irradiation with hfb a 1 : 2adduct. Replacement of co-ordinatedCO in the adduct by P(OCH2)3CMe gave crystals of (9)[Ru(CO)2P(OCH2)3CMe}(C6H8)(C4F6)2] suitable for X-ray crystallography. Crystals of (9) are monoclinic, space group P21/c, with Z= 4 in a unit cell of drmensions: a= 8.875(5), b= 17.841 (9), c= 16.517(5)Å, β= 94.51(3)°.

Ir(CO)2(PPh3)2, Rh(CO)2(PPh3)2), but the use of an excess of [Fe(CO)2(η-C5H6)]− leads to substitution of one fluorine atom on each of the double bonds. The complex having M = Mn(CO)5 reacts with [Pt(PPh3)4] to afford the derivative [(C7F7)Mn(CO)4(PPh3)}Pt(PPh3)2}], and the compound where M = Ir(CO)2(PPh3)2 undergoes an oxidative addition reaction with acetyl chloride. Oxidative coupling products have been

reactive intermediates with bromine, followed by an aqueous process, leads to γ,δ-unsaturatedacids. Reaction of the intermediates with iodomethane or benzyl bromide gives γ,δ-unsaturated ketones after carbonyl insertions. Benzoyl chloride is also observed to react with the postulate intermediates to form γ,δ-unsaturated benzophenone derivatives.

The allylic cations, when reacted with P (C6H5)3, yield uncomplexed (2-en-l-yl)triphenylphosphonium salts in good yields, while treatment of the dienyl cations with P(C6H5)3 leads to the quantitative formation of (2,4-diene-l-yl)triphenylphosphonium ions still coordinated
