一般描述

2,3-二甲基-1,3-丁二烯 (DMBD) 是一种共轭二烯。它与 2-硫代-3-氯丙烯酰胺在热、催化和微波条件下发生 Diels Alder 环加成反应。在无溶剂条件下与 3-乙酰基、3-氨基甲酰基和 3-乙氧基羰基香豆素发生热 [4 + 2] 环加成反应。在二氯化铁基催化剂存在下，DMBD 参与聚合反应。

应用

用扫描隧道显微镜和傅里叶变换红外光谱研究了 1，3-二烯在 Si (001) 表面的反应。
它可用于以下过程：
  • 在钴催化剂存在下通过 1，4-氢化丁二烯基化制备相应的的 1-芳基取代 1，3-二烯的 1，3，6-三烯衍生物。
  • 与 gem-氰基硝基乙烯反应合成 6-芳基（杂环芳基）-3,4-二甲基-1-硝基-1-氰基-3-环己烯。
  • 在研究 2，5-二苯基特鲁洛芬的二溴加合物的光解反应过程中，作为卤素捕集器。
