Abstract:
A process for the preparation of 3-alkoxybenzene compounds of the formula: ##STR14## wherein X represents Cl, Br, CO.sub.2 H, or a 1-alkyl-5-hydroxypyrazole-4-carbonyl moiety of the formula: ##STR15## R represents a C.sub.1 -C.sub.4 alkyl group unsubstituted or substituted with a C.sub.1 -C.sub.4 alkoxy or C.sub.1 -C.sub.4 alkylthio group or with a 3-6 membered alicyclic moiety having one oxygen or sulfur atom and 2-5 carbon atoms or represents a 3-6 membered alicyclic moiety having one oxygen or sulfur atom and 2-5 carbon atoms;R"" represents H or C.sub.1 -C.sub.4 alkyl; andR' and R'"" each independently represents C.sub.1 --C.sub.4 alkyl;which process comprises causing a 3-chlorobenzene compound of the formula: ##STR16## wherein X and R'"" are as defined hereinabove to react with an alkali metal alkoxide compound of the formula:RO.sup.- MwhereinR is as defined hereinabove andM.sup.+ represents lithium, sodium, or potassium cationin a liquid medium, optionally in the presence of a phase transfer catalyst, at a temperature of about 20.degree. C. to about 110.degree. C.
