Process for preparing 2-chloro-3-alkoxy-4-alkylsulfonyl-benzoic acids and esters

1-Halo-2-chloro-3-alkoxy-4-alkylsulfonylbenzene and 1-halo-2,3-dichloro-4-alkylsulfonylbenzene compounds were converted to compounds having hydroxycarbonyl or alkoxycarbonyl substituents in place of the 1-halo substituent by reaction with carbon monoxide

Process for preparing 1-alkyl-4-(2-chloro-3-alkoxy-4-alkylsulfonylbenzoyl)-5-hydroxypyrazole and related compounds

Herbicidal 1-alkyl-4-(2-chloro-3-alkoxy-4-alkylsulfonylbenzoyl)-5-hydroxypyrazole compounds, as well as 1-halo-2-chloro-3-alkoxy-4-alkylsulfonylbenzene compounds and 2-chloro-3-alkoxy-4-alkylsulfonylbenzoic acid compounds, were prepared in good yield by t
