electron-withdrawing groups undergo rapid reactions with a variety of alcohols and secondary amines to afford the corresponding esters and amides, respectively, in high yields, when treated with NaCN or acetonecyanohydrin and base under ambient reaction conditions. In case of α,β-unsaturated aldehydes, simultaneous reduction of the CC bond along with esterification occurred to produce the saturated esters in high

Since esters are important organic synthesis intermediates, an environmentally friendly oxone catalyzed-esterification of carboxylic acids with alcohols has been developed. A series of carboxylic acidesters are obtained in high yield. This strategy requires mild reaction conditions, providing an attractive alternative for the construction of valuable carbonyl esters. Electron-rich and electron-deficient

Phenylacetonitrile and itsderivatives were treated with alcohols in the presence of potassium iodide and iodine affording the corresponding benzoate esters via degradation, oxidation and esterification under mild conditions. The products were characterised by IR, 1H NMR, MS and elemental analysis.

A facile coupling process between aldehydes and alcohols to afford unsymmetrical ester compounds is presented herein. This reaction is complementary to the Tishchenko reaction and provides an evolved procedure to access unsymmetrical esters under very mild conditions. Various aldehydes and alcohols are suitable for this transformation. Using the sacrificial trifluromethyl ketones renders the reaction
