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.
