, p. 1237 - 1247 (2007/10/03)
Reduction of ethyl 3-methyl-, 3-isopropyl- and 3-n-pentyl-3-[dimethyl(phenyl)silyl]propanoates 4 with DIBAL to the aldehydes 5, enol trifluoromethanesulfonate (triflate) formation using trifluoromethanesulfonic (triflic) anhydride and 2,6-di-tert-butylpyridine, and elimination using LDA, gives the propargyl silanes 8. The esters 4 could also be prepared enantiomerically enriched (11), and the final products are the enantiomerically enriched propargyl (homochiral) silanes 14.

Aliphatic silyl thioketones containing an α-hydrogen atom undergo enethiolization to Z-α-silyl enethiols 2. Compounds 2 react with a variety of halides R3X to give open-chain α-silyl vinyl sulfides 3. Protiodesilylation of 3 was achieved upon treatment with fluoride ion to give vinyl sulfides 4. Reaction of 3 with Grignard reagents, in the presence of an appropriate nickel catalyst, results in a series of vinylsilanes 5 with a specific geometry.
A regiodefined synthesis of α-trimethylsilyl ketones catalyzed by rhodium(I) hydride complex
Sato, Susumu,Matsuda, Isamu,Izumi, Yusuke
, p. 71 - 88 (2007/10/02)
Regiodefined synthesis of α-trimethylsilyl ketones is attained by one of three different routes: isomerization of β-trimethylsilyl allyl alcohols (route A), isomerization of β'-trimethylsilyl allyl alcohols (route B), and dehydrogenation of β-trimethylsil
