The reaction of ,N-diethylamino(cyclohexylphosphino)dimethylsilane 1 w
ith the benzene solvate of copper(I) trifluoromethylsulfonate furnishe
s the title complex 2, which has been structurally characterized by X-
ray diffraction; the same product results on conversion of bis(cyclohe
xylphosphino)dimethylsilane 3 with copper(I) trifluoromethylsulfonate
in the presence of lithium diisopropylamide as an auxilliary base.
