- 論文の詳細を見る
The selective cross-acyloin condensation, where 1-hydroxy-2-ones were obtained selectively from formaldehyde and a wide variety of other aldehydes, was achieved by using 3-ethylbenzothiazolium bromide as a catalyst in the presence of triethylamine. The present reaction is expected to afford a novel and facile method for the synthesis of 1-hydroxy-2-ones. A mechanism accounting for the selective formation of 1-hydroxy-2-one was proposed based on the results obtained by examining the reactions between formaldehyde and P-substituted benzaldehydes. It is of much interest in the mechanism that two catalytic species show an inverse selectivity toward aldehydes.
