The present invention relates to a practical and cost-effective method for the synthesis of 5-chloromethylated 2,3-dialkoxy-6-alkyl-1,4-benzoquinones by direct chloromethylation of the corresponding 2,3-dialkoxy-6-alkyl-1,4-benzoquinones. The invention further relates to a method for the preparation of 5-chloromethylated 2,3-dialkoxy-6-alkyl-1,4-benzoquinones starting from a 3,4,5-trialkoxy-1-alkyl-benzene.
本发明涉及一种通过直接将相应的2,3-二烷氧基-6-烷基-1,4-苯醌进行氯甲基化来合成5-氯甲基化的2,3-二烷氧基-6-烷基-1,4-苯醌的实用且具有成本效益的方法。本发明还涉及一种以 3,4,5-三烷氧基-1-烷基苯为原料制备 5-氯甲基化 2,3-二烷氧基-6-烷基-1,4-苯醌的方法。
