Abstract
1331664 Hydroxybenzaldehydes SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 10 May 1972 [28 Sept 1971] 45110/71 Heading C2C Hydroxybenzaldehydes of the formula wherein R<SP>1</SP> is H, a monovalent cation, or alkyl group, R is a halogen atom, OH, alkyl or alkoxy group, and n is 0, 1 or 2; are obtained by reacting a compound of the formula with a base in the presence of a polar aprotic organic liquid having a dielectric constant of at least 20 at 25‹ C. and containing no hydrogen atoms in the molecules thereof which are capable of forming hydrogen bonds with negatively charged species. Preferred bases are hydrides, alkoxides or carbonates of alkali metals or alkaline earth metals. Specified solvents are dimethylformamide, dimethylacetamide, dimethyl sulphoxide, tetramethyl urea, hexamethyl phosphoramide and tetramethylenesulphone. Examples are given for the production of the compounds.
