An object of the present invention is to produce an α-hydroxyketone compound easily and effectively. Provided is a process for producing an α-hydroxyketone compound comprising a stirring step of stirring one or more aldehyde compounds or polymers thereof in the presence of a base and an imidazolinium salt represented by the formula (1):
wherein R
1
and R
2
each independently represent a hydrogen atom, an alkyl group optionally having a substituent or an aryl group optionally having a substituent, or R
1
and R
2
are bound to each other to form a ring together with carbon atoms to which they bind, R
3
and R
4
each independently represent an aryl group having one or more electron withdrawing groups, and X
−
represents an anion.
本发明的目的是轻松有效地制备α-羟基酮化合物。提供了一种制备α-羟基酮化合物的方法,包括在碱和式(1)表示的咪唑啉盐存在下搅拌一种或多种醛化合物或其聚合物的搅拌步骤,其中R1和R2各自独立表示氢原子,具有取代基的烷基或具有取代基的芳基,或R1和R2彼此结合形成环,与它们结合的碳原子一起,R3和R4各自独立表示具有一个或多个电子吸引基团的芳基,X-表示阴离子。
