摘要

1-Ethynyl-2-phenyltetramethyldisilanes HCCSiMe2SiMe2C6H4X [X= NMe2 (1), H (2), CH3 (3), Br (4), CF3 (5)] are accessible from ClSiMe2SiMe2Cl, BrMgC6H4X and HCCMgBr in a two step Grignard reaction. The crystal structure of 1 as determined by single crystal X-ray crystallography exhibits a nearly planar PhNMe2 moiety and an unusual gauche array of the phenyl and the acetylene group with respect to rotation around the Si–Si bond.
