Halogen Oxidation and Nitrosylation of Mixed Ligand Molybdenum and Tungsten Tricarbonyls

(L-L)(Ph3E)Mo(CO)3 (L-L = o-phen or 2,2'-bipy; E = As or Sb) after bromine or iodine oxidation yield X (X = Br, I) derivatives.Under similar conditions Ph3P is displaced from (L-L)(Ph3P)Mo(CO)3 to produce dimeric (L-L)Mo(CO)3X2.Chlorine swept benzene displaces both CO and Ph3P from (L-L)(PH3P)Mo(CO)3 and only CO from (L-L)(Ph3E)Mo(CO)3 to yield (L-L)MoCl4 and Cl, respectively.Nitrosylation of (L-L)(Ph3E')M(CO)3 (M = Mo, W; E' = P, As, Sb) using NOCl gives a mixture of (L-L)M(NO)2Cl2 and Cl; while 2 derivatives are recovered when free NO is used.The complexes have been characterised by elemental analysis, ir, conductivity and magnetic measurements.
