 Title    Efficiency of Photosubstitution of Arenetricarbonylchromium(O) Complexes  
 Abstract    The quantum efficiency of the formation of (arene)Cr(CO)2(pyridine) (arene = benzene, mesitylene) is reported as a function of the irradiation wavelength of (arene)Cr(CO)3 and as a function of pyridine concentration. The quantum efficiency is independent of pyridine concentration in the range 0.008-0.17 M. The quantum efficiency is 0.72 ± 0.07 upon 313, 366, or 436 nm irradiation. The (arene)Cr(CO)3 complexes are found to quench triplet excited benzil at a diffusion controlled rate and the quenching is accompanied by reaction of the (arene)Cr(CO)3. The reaction product which presumably arises from CO release is the same as that obtained from direct irradiation of (arene)Cr(CO)3 in the presence of benzil. However, the triplet sensitized reaction occurs with a quantum efficiency of only 0.15 ± 0 .0 5 in contrast to the high substitution efficiency (0.72 ±0.07) of (arene)Cr(CO)3 upon direct irradiation.

 Title    Reaktionen von Metallcarbonylverbindungen mit Diaziridin 1 Reactions of Metal Carbonyls with Diaziridine  
 Abstract    Cyclic carbamoyl complexes (2) and (3) result from the reaction of metal carbonyl hydrides with 3,3-pentamethylen diaziridine (1). 1 is cleaved at the metal by reaction with substituted metal carbonyls of Mo and W formally into 'nitrene' and cyclohexanone imine, which are isolated as isocyanate and ketimine complexes, respectively. 1 forms adducts with cobalt and nickel(II) chlorides.

 Title    Methylen Verbindungen von Nichtmetallen, III [1] Metallcarbonyl-Komplexe mit methylenverbrückten Diphosphor-Liganden Methylene Compounds of Non-Metals, III [1] Metal Carbonyl Complexes of Methylene-Bridged Diphosphorus Ligands  
 Abstract    Compounds of the type R2PCH2PR2 (R = Pr«0, Me2N) react with cis-LM(CO)4 (L = Bicyclo[2,2,l]hepta-2,5-dien; M = Cr, Mo, W) complexes to yield cis-substituted [R2PCH2PR2]M(CO)4 derivatives. The structure of the molybdenum compound, [(Pr i O)2PCH2P(OPr i)2]Mo(CO)4, has been determined. Diphosphorus ligands of the type R2P(S)CH2PR2 (R = F, Pr*0) are monodentate and form [R2P(S)CH2PR2]2Mo(CO)4 complexes, whereas the compound (Me2N)2P(S)CH2P(NMe2)2 acts as a bidentate ligand.
