Abstract The racemic acetyltriorganylsilanes MePh (Me 3 C) SiC (O) Me (1) and MePh (Me 3 SiCH 2) SiC (O) Me (2) were prepared from MePhSiCl 2. Compounds 1 and 2 are available by two different three-step syntheses. Method a: MePhSiCl 2→ MePh (Me 3 C) SiCl (5)→ MePh (Me 3 C) SiC (Me) SCH2CH2CH2S (7)→ 1 (total yield 36%); MePhSiCl 2→ MePh (Me 3 SiCH 2) SiCl (6)→ MePh (Me 3 SiCH 2) SiC (Me) SCH2CH2CH2S (8)→ 2 (total yield 30 ...
