The photochemical conversion of M(CO)6 (M = Cr, Mo, W) to M(CO)5X- (X = halogen) across a hexane/water interface leads to a separation of the reactant and product. This process may be of general importance for synthetic applications. Under suitable conditions inner-filter effects and secondary photolysis can be avoided.

The rate constants for the halogen-atom-transfer reactions between transition-metal complex anion radicals (L(OC) x−1 M •− ) and up to 14 halogenated methanes and ethanes (RX) were measured in a flowing afterglow apparatus

The reaction of the tetraethylammonium salts of the halopentacarbonyl anions the Group VIA metals, with aryl and alkyl isonitriles affords mono-, bis-, and tris-isonitrile derivatives of the metal carbonyls in ratios which can be predetermined by suitable choice of reactants and reaction conditions. The mechanism is discussed.

The first examples of co-ordination complexes containing a phospha-alkene are described; n.m.r. studies on cis-M(CO)4L2(M = Cr,Mo,W), trans-RhCl-(PPh3)2L, trans-RhCIL2(CO), Rh(η5-C9H7)L2, cis-PtX2L2(X = Cl,I,Me), and cis- and trans-PtCl2(PEt3)L, [L = P(mesityl)CPh2], suggest that co-ordination to the metal is via the phosphorus lone pair.
