of 4-allyl compound was formed. In contrast, N-benzyl-2,6-xylidine did not rearrange in the presence of zinc chloride but the required 4-benzyl-2,6-xylidine was obtained by direct benzylation of 2,6-xylidine. The 4-allyl-and 4-benzyl-2,6-xylidines were converted smoothly to the corresponding bromobenzenes by the Sandmeyer reaction.
Ñ在回流的二甲苯中并氯化锌单独加热,但重新被安排至4-烯丙基-2,6-二甲代苯胺时-烯丙基-2,6-二甲代苯胺不变。当单独加热盐酸盐时,主要反应是离解为烯丙基氯和二甲苯胺,并且仅形成痕量的4-烯丙基化合物。相反,在氯化锌存在下,N-苄基-2,6-二甲苯胺不会重排,但是通过2,6-二苯甲基的直接苄基化获得了所需的4-苄基-2,6-二甲苯胺。通过Sandmeyer反应将4-烯丙基和4-苄基-2,6-二甲基吡啶平稳地转化为相应的溴苯。
