PURPOSE:To easily obtain the subject compound in high conversion and yield by using a specific vanadium compound as a catalyst and contacting a specific alicyclic olefin with an O2-containing gas in the presence of a primary alcohol, etc., thereby oxidizing the olefin under mild condition. CONSTITUTION:The objective compound is produced by contacting and oxidizing an alicyclic olefin of formula I [R<4> and R<5> are each H, alkyl, benzoyloxymethyl, benzoyloxyethyl or R<4> and R<5> together form a (double-bond) ring] (e.g. 2- norbornene) with an O2-containing gas in the presence of a primary and/or secondary alcohol (e.g. isopropanol) using a vanadium compound catalyst of formula III (R<1> and R<2> are each lower alkyl, aryl or alkoxycarbonyl; R<3> is lower alkyl, alkenyl, aryl, H, halogen, etc.; R<2> and R<3> may together form a ring) (e.g. the compound of formula II). The conversion of the objective compound can be further improved by carrying out the reaction in the presence of a synthetic zeolite. |
