Abstract: | The compounds M(CO)5 · THF (M = Cr, Mo, W) react with sodium mercaptide, NaSR (R = C6F5, C6H5, C2H5), to give the mercapto-pentacarbonylmetallate anions [M(CO)5 · · SR]?. The preparation of some pentafluorophenylthio complexes, e. g. [(C6H5)3P]2MSC6F5(M = Cu, Ag, Au), [(C6H5)3P]2Hg(SC6F5)2, is reported. |
