An object of the present invention is to provide a new process which can produce a carboxylic acid ester from an aldehyde. The object is achieved by a process for producing a carboxylic acid ester, including the step of mixing a compound represented by the formula (2-1): (wherein R2 represents an alkyl group optionally having a substituent, or the like; R3 and R4 each represent independently an alkyl group optionally having a substituent, or the like, or R3 and R4 are taken together to form a divalent hydrocarbon group optionally having a substituent, or the like; Y represents a group represented by -S- or a group represented by -N(R5)-; R5 represents an alkyl group optionally having a substituent, or the like, or R5 is taken together with R4 to form a divalent hydrocarbon group optionally having a substituent; and X- represents an anion), a base, an alcohol, oxygen and an aldehyde to oxidize the aldehyde.
本发明的一个目的是提供一种新的过程,可以从醛中产生羧酸酯。该目的通过一种生产羧酸酯的过程实现,包括混合以下公式表示的化合物(2-1)的步骤:(其中R2代表一个烷基基团,可选地具有取代基,或类似物;R3和R4分别独立地代表一个烷基基团,可选地具有取代基,或类似物,或者R3和R4结合在一起形成一个二价碳氢基团,可选地具有取代基,或类似物;Y代表一个由-S-表示的基团或由-N(R5)-表示的基团;R5代表一个烷基基团,可选地具有取代基,或类似物,或R5与R4结合在一起形成一个二价碳氢基团,可选地具有取代基;X-代表一个阴离子),一种碱,一种醇,氧气和一种醛来氧化该醛。
