Yoshino, Hideaki,Kobata, Masami,Yamamoto, Yuhei,Oshima, Koichiro,Matsubara, Seijiro
, p. 1224 - 1224 (2004)
Ketones were transformed into alkenes via methylenation with bis(iodozincio)methane and ionic liquid, 1-butyl-3-methyl-imidazolium hexafluorophosphate ([bmim][PF6]) in the absence of additional metal salt such as titanium chlorides.

Olefination of carbonyl compounds with gem-dizincio-alkanes, bis(iodozincio)methane, 1,1-bis(iodozincio)ethane, and bis(bromozincio)methyltrimethylsilane, afforded the corresponding olefins in good to excellent yields.
Stereoelectronic effects: Perlin effects in cyclohexane-derived compounds
Jung, Sebastian T.,Nickisch, Roman,Reinsperger, Tony,Luy, Burkhard,Podlech, Joachim
, (2020/12/04)
Stereoelectronic effects in cyclohexanones, methylenecyclohexanes, spiro, and epoxy compounds of cyclohexanes and further derivatives were investigated by measuring 1JC,H coupling constants and by identification of Perlin effects, th
Contra-thermodynamic Olefin Isomerization by Chain-Walking Hydrofunctionalization and Formal Retro-hydrofunctionalization

We report a contra-thermodynamic isomerization of internal olefins to terminal olefins driven by redox reactions and formation of Si-F bonds. This process involves chain-walking hydrosilylation of internal olefins and subsequent formal retro-hydrosilylation. The process rests upon the high activities of platinum hydrosilylation catalysts for isomerization of metal alkyl intermediates and a new, metal-free process for the conversion of alkylsilanes to alkenes. By this approach, 1,2-disubstituted and trisubstituted olefins are converted to terminal olefins.
