New alkyl (4-halomethyl)iminobenzoates of the formula ##STR1## and their HCl or HBr salts, R denoting C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxyethyl and X denoting Cl or Br. These compounds are prepared by reaction of p-cyanobenzyl chloride or p-cyanobenzyl bromide with a C.sub.1 -C.sub.4 -alcohol or C.sub.1 -C.sub.4 -alkoxyethanol in the presence of hydrogen chloride or bromide. The new imines serve as intermediate products, inter alia for the preparation of optical brighteners of the bisbenzoxazolylstilbene class.
化合物的名称为新的烷基(4-卤甲基)亚胺基苯甲酸酯及其HCl或HBr盐,其化学式为##STR1## 其中R代表C.sub.1-C.sub.4烷基或C.sub.1-C.sub.4烷氧乙基,X代表Cl或Br。这些化合物是通过在氯化氢或溴化氢存在下,将p-氰基苯甲酰氯或p-氰基苯甲酰溴与C.sub.1-C.sub.4醇或C.sub.1-C.sub.4烷氧乙醇反应制备而成。这些新的亚胺基化合物可作为中间体,用于制备双苯并噁唑基苯乙烯类光亮剂等。
