A kinetic study of the reaction of Mn and Re carbonyls with some bis(N,N-dialkylselenocarbamoyl) selenides
Using a 366 nm source, irradiation of a CH2Cl2 solution of M2(CO)10 (MMn, Re) and an excess of (LL):a 1:1 mixture of RIRIINC(Se)Se(Se)CNRIRII and RIRIINC(Se)Se3(Se)CNRIRII [if RI RII C2H5(LL) (Et2dsc-dscEt2), if RIRIIN = morpholyl (LL) = (modsc-dscmo), if RICH3, RIIC6H5 (LL) = (Mephdsc-dscMeph) quantitatively produces [M(CO)4L], where The photochemical reaction is extensively studied, the quantum yields and the rate constants are determined. A SN1-type mechanism is proposed, involving homolytic MM bond fission as the rate determining step.
