Abstract
Compounds containing halogenmethyl groups, in addition to alkoxy or alkylthio groups, are made by causing a benzene derivative which contains at least one alkoxy or alkylthio group, and either contains no further substituent, or contains as further substituent alkyl, halogen, or a nitrogroup, to react with formaldehyde in the presence of a concentrated hydrogen halide solution. According to the conditions of the reaction, either one or two halogenmethyl groups enter the molecule. In examples, by treating with an aqueous formaldehyde solution saturated with hydrochloric acid, (1) anisol yields 2 : 4-di(chlormethyl)-anisol, (2) m-chloranisol yields a mono-chlormethyl derivative, (3) p-cresolmethylether yields 3-chlormethyl-4-methoxytoluene, (4) hydroquinone-dimethylether yields the 2 : 5-dichlormethyl derivative (5) o-nitroanisol yields a mono-chlormethyl derivative, (6) p-thiocresolmethylether yields a monochlormethyl derivative, and (7) thiophenol-methylether yields the 2 : 4-di(chlormethyl) derivative. Specification 17118/99, [Class 2, Acids and salts, Organic &c.], is referred to.
