چکیده

1-Ethyl-3-methylimidazolium acetate is introduced as a robust organocatalyst for solvent-free cyanosilylation of carbonyl compounds with trimethylsilyl cyanide (TMSCN). The catalyst loading can be reduced to as low as 0.1-0.0001 mol % under mild reaction conditions, giving considerably high TOF values from 10,843 h-1 to 10,602,410 h-1 in the field of organocatalyzed transformations. The present protocol not only tolerates with extensive carbonyl compounds but also provides somewhat insight into the mechanism of ionic liquids (ILs)-catalyzed reactions.

Asymmetric counteranion-directed Lewis acid organocatalysis for the scalable cyanosilylation of aldehydes

Due to the high versatility of chiral cyanohydrins, the catalytic asymmetric cyanation reaction of carbonyl compounds has attracted widespread interest. However, efficient protocols that function at a preparative scale with low catalyst loading are still rare. Here, asymmetric counteranion-directed Lewis acid organocatalysis proves to be remarkably successful in addressing this problem and enab...

Enantioselective cyanosilylation of ketones catalyzed by a chiral oxazaborolidinium ion.

The chiral oxazaborolidinium salt 1 (X = TfO) is an excellent catalyst for the cyanosilylation of methyl ketones promoted by trimethylsilyl cyanide and diphenylmethyl phosphine oxide as co-reactants (to generate Ph(2)MePOTMS(N=C:) as a reactive intermediate). The face selectivity of this reaction parallels that previously observed for the corresponding reaction of aldehydes. A unifying and rati...

Highly enantioselective cyanosilylation of aldehydes catalyzed by a chiral oxazaborolidinium ion.

The chiral oxazaborolidinium salts 1 and 2 are excellent catalysts for the enantioselective cyanosilylation of a wide variety of aldehydes (see Table 1) using trimethylsilyl (TMS) cyanide and triphenylphosphine oxide as the source of a new reactive cyanide donor. This donor appears to be the isocyanophosphorane Ph3P(OTMS)(N=C:) (4). The novel process described herein has several advantages: pre...
