O-acylation of ketoximes of the furan and thiophene series in the liquid-solid body system under interphase catalysts conditions

The acrylation of 2-furanyl- and 2-thienylalkylketoximes by acyl chlorides in a two-phase catalytic system (solid K2CO3-C6H6-18-crown-6) at room temperature leads to a selective formation of the corresponding O-acetylketoximes in the form of a mixture of E- and Z-isomers.
