Disclosed is a method for producing a biphenyl-skeleton-containing epoxy resin represented by Formula (1) described below including a step of allowing polyvalent hydroxy biphenyl obtained by a production step including a regioselective cross-coupling reaction to react with epihalohydrin.
(In the formula, k1 and 11 each represent an integer of 0 to 4, m and n each represent an integer of 1 to 5, R1 and R2 each independently represent a hydrocarbon group having 1 to 10 carbon atoms which may have a substituent group, and R1 and R2 may be identical to each other or different from each other. (Provided that left and right phenyl structures of a biphenyl skeleton are different from each other.)
本发明公开了一种生产由下述式(1)表示的含
联苯骨架环氧
树脂的方法,该方法包括以下步骤:使通过包括区域选择性交叉偶联反应的生产步骤获得的多价羟基
联苯与表卤代烃反应。
(式中,k1 和 11 分别代表 0 至 4 的整数,m 和 n 分别代表 1 至 5 的整数,R1 和 R2 分别独立地代表具有 1 至 10 个碳原子的烃基,该烃基可以具有取代基,R1 和 R2 可以彼此相同或彼此不同。(前提是
联苯骨架的左右苯基结构彼此不同)。
