Suzuki, Kosuke,Sugawa, Midori,Kikukawa, Yuji,Kamata, Keigo,Yamaguchi, Kazuya,Mizuno, Noritaka
, p. 6953 - 6961 (2012)
Efficient polyoxometalate (POM)-based Lewis acid-base catalysts of the rare-earth-metal-containing POMs (TBA6RE-POM, RE = Y3+, Nd3+, Eu3+, Gd3+, Tb3+, or Dy 3+) were designed and
Rasta resin-PPh3BnCl and its use in chromatography-free carbonyl cyanosilylation reactions
Teng, Yan,Toy, Patrick H.
, p. 551 - 554 (2011)
Rasta resin-PPhnCl, a new heterogeneous polystyrene-based phosphonium salt, has been synthesized and used to catalyze cyanosilylation reactions of aldehydes and ketones. It was found to be more efficient as a catalyst than a similar heterogeneous phosphon
Synthesis of magnetically recoverable imidazolium hydrogen carbonate and its application as an N-heterocyclic carbene catalyst to cyanosilylation of aldehydes and ketones
Fujii, Akira,Choi, Jun-Chul,Fujita, Ken-ichi
, p. 1515 - 1518 (2017)
We prepared a magnetically recoverable imidazolium hydrogen carbonate by immobilizing an imidazolium hydrogen carbonate on magnetite and applied it as an N-heterocyclic carbene catalyst to the cyanosilylation of aldehydes and ketones. By employing the magnetite-supported imidazolium hydrogen carbonate as a catalyst, the cyanosilylation proceeded at 60?°C to provide the corresponding trimethylsilylated cyanohydrin in a fair chemical yield. Moreover, after the reaction, the magnetic catalyst was readily recovered by use of an external magnet and could be reused up to five times.
OXIDATION OF α,β-UNSATURATED ALDEHYDES
Bal, Balkrishna S.,Childers, Wayne E.,Pinnick, Harold W.
, p. 2091 - 2096 (1981)
A variety of methods for the conversion of α,β-unsaturated aldehydes to the corresponding acids have been explored.The best approach uses sodium chlorite and gives the desired transformation even in systems where steric hindrance and/or sensitive functionality are present.
A tricyclic aluminum alkoxide catalyst for aldehyde trimethylsilylcyanation
Raders, Steven M.,Verkade, John G.
, p. 5317 - 5321 (2009)
Trimethylsilylcyanation of aldehydes is efficiently accomplished with a low concentration of catalyst 1 under mild conditions in acetonitrile. This protocol tolerates a variety of electron-rich, neutral, and deficient aryl, heterocyclic, and alkyl aldehyd
An improved synthesis of cyanohydrins in the presence of solid LiClO4 under solvent-free conditions
Azizi, Najmedin,Saidi, Mohammad R.
, p. 283 - 285 (2003)
Several cyanohydrins were synthesized by the reaction of trimethylsilyl cyanide with carbonyl compounds in the presence of solid lithium perchlorate in high yields under solvent-free conditions.

An efficient method for the addition of trimethylsilyl cyanide (TMSCN) to various aldehydes and ketones has been described using Fe(Cp)2PF6 (2.5 mol%) as a catalyst under solvent free condition. Excellent yields of trimethylsilylethe
Gold(III)-catalyzed cyanosilylation of ketones and aldehydes
Woo, Kyung Cho,Sung, Min Kang,Medda, Amiya K.,Lee, Jungkyu K.,Choi, Insung S.,Lee, Hee-Seung
, p. 507 - 510 (2008)
Gold(III) chloride was found to be a highly efficient catalyst for the cyanosilylation of various ketones and aldehydes. The reactions were complete within 30 minutes at room temperature in the presence of only one mol% gold(III) chloride, yielding the co
