The selective synthesis of functional alkynylsllanes RC=C(SiMe 2)m,-X (m = 1, 3) was investigated. Monofunctionalization with or without protecting groups gave moderate to good yields of alkynyldimethylmonosilanes RC=CMe2SiX [R = Ph, X = Cl. (1), NEt 2 (2), OMe (3), H (4), Br (5), I (6), Cp (8), C5H 4Li (10), Ph (11); R = Pr, X = Ph (12)]. Compounds 4 and 8 were converted into the (alkyne)transition-metal complexes 4-Cp2Mo 2(CO)4 (13) and 8-Co2(CO)6 (14), respectively, which were characterized by X-ray diffraction. Stepwise extension and functionalization of the silane chain starting from 1chloro-2-(diethylamino) tetramethyldisilane (Et2NMe2Si-SiMe2Cl) yielded the trisilanes Ph-(SiMe2J3-X [X = NEt2 (18), OMe (19), Cl (20), H (21), C=CPh (22), C=CPr (23)]. The synthesized compounds were characterized by NMR and IR spectroscopy, 4, 11, 13, and 14 also by UV/Vis spectroscopy.
