P(RNCH2CH2)N: Efficient catalysts for the cyanosilylation of aldehydes and ketones
Fetterly, Brandon M.,Verkade, John G.
, p. 8061 - 8066 (2005)
The 1,2-addition of trialkylsilylcyanides to aldehydes and ketones produces the corresponding protected cyanohydrins in good to excellent yields when carried out at 0°C to room temperature in the presence of catalytic amounts of the nonionic strong base P(RNCH2CH2)N (R = Me, i-Pr) in THF. These catalysts are easily removed from the product by hydrolysis or column filtration through silica gel.

Large-scale isolation of nanocrystals of rare-earth-polyoxometalates (RE-POMs) catalysts is important in fundamental research and applications. Here, we synthesized a family of monomeric RE-POMs by the self-assembly of Ta/W mixed-addendum POM {P2/su
Solvent-free synthesis of cyanohydrin derivatives catalysed by triethylamine
Baeza, Alejandro,Najera, Carmen,Retamosa, Ma. De Gracia,Sansano, Jose M.
, p. 2787 - 2797 (2007/10/03)
A very simple one-step environmentally friendly procedure for the synthesis of O-substituted cyanohydrins from aldehydes and ketones, in the absence of solvent, employing minimum amounts of the corresponding cyanides has been optimised. Aldehydes react more rapidly than ketones using triethylamine as catalyst offering in both cases almost quantitative yields of the corresponding O-trimethylsilyl, O-methoxycarbonyl, O-benzoyl and O-acetyl cyanohydrins.

P(MeNMCH2CH2)3N: An effective catalyst for trimethylsilycyanation of aldehydes and ketones
Wang, Zhigang,Fetterly, Brandon,Verkade, John G
, p. 161 - 166 (2007/10/03)
The title non-ionic phosphazane base promotes the trimethylsilycyanation of alkyl and alkyl aldehydes and ketones in moderate to high yields at room temperature. 29Si-NMR spectral evidence for the intermediacy of a phosphazane phosphorus-silicon adduct is presented.
Calcined MgAlCO3-HT catalysed cyanosilylation of carbonyl compounds and nucleophilic ring opening of oxiranes using TMSCN
Choudary,Narender,Bhuma
, p. 2829 - 2836 (2007/10/02)
Nucleophilic addition of TMSCN to carbonyl compounds is found to be catalysed efficiently using hydrotalcite as a solid base. The catalyst is also found to be active in the nucleophilic ring opening of oxiranes giving high regioselectivity.
