    Abstract: PROBLEM TO BE SOLVED: To obtain a catechol monoether or catechol, both of which are useful as intermediates for synthesizing medicines, flavors, and seasonings, simply and economically, by reacting a specific oxygen-containing cyclohexane compound in the presence of a specific catalyst. SOLUTION: A catechol monoether shown by formula III is obtained by the reaction of (A) a compound shown by formula I (R is a 1-8C hydrocarbon group; R and R are each H or R ) or a compound shown by formula II in the presence of (B) a catalyst in which palladium (B2 ) is supported on vanadium oxide carrier (B1 ) (e.g. a catalyst which contains B2 at 0.2-5 wt.% per sum of B1 and B2 calculated as metal, whose BET surface area is 10-300 m /g, which has an average pore size of 2-100 nm and a pore volume of 0.1-1 ml/g, and which crystal transformation of B1 is monoclinic system at 60-100%) in gas phase. The catechol shown by formula IV is obtained also by the reaction in water.
