- 中文摘要: Oxidative addition of diphenyl disulfide to the coordinatively unsaturated [ Mn(CO)/sub 5/ ] /sup -/ led to the formation of low-spin, six-coordinate cis- [ Mn(CO)/sub 4/(SPh)/sub 2/ ] /sup -/. The complex cis- [ PPN ] [ Mn(CO)/sub 4/(SPh)/sub 2/ ] crystallized in monoclinic space group P2/sub 1//c with a=9.965(2).ANG., b=24.604(5).ANG., c=19.291(4).ANG., .beta.=100.05(2).degree., V=4657(2).ANG./sup 3/, and Z=4; final R=0.036 and R/sub w/=0.039. Thermal transformation of cis- [ Mn(CO)/sub 4/( SPh)/sub 2/ ]/sup -/ to [ (CO)/sub 3/Mn(.mu.-SPh)/sub 3/Mn(CO)/sub 3/ ]/sup -/ was completed overnight in THF at room temperature. Additionally, reaction of [ Mn(CO)/sub 5/ ] /sup -/ and PhSH in 1:2 mole ratio also led to cis- [ PPN ] [ Mn(CO)/sub 4/ (SPh)/sub 2/ ] . Presumably, oxidative addition of PhSH to [ Mn(CO)/sub 5/ ] /sup -/ was followed by a Lewis acid-base reaction to form cis- [ Mn(CO)/sub 4/(SPh)/sub 2/] /sup -/ with evolution of H/sub 2/.
