Ir-catalysed borylation of phthalonitrile produces both 4-(Bpin)phthalonitrile (1) and 3,5-bis(Bpin)phthalonitrile (2), which are potential divergent intermediates for the synthesis of functionalized phthalocyanines. To exemplify the utility of 2, we have prepared a series of 3,5-bis-arylphthalonitriles that in turn undergo sterically controlled regioselective cyclotetramization to give previously unknown C4h 1,3,8,10,15,17,22,24-octaarylphthalocyanines.
铱催化的邻苯二甲腈硼化反应生成了 4-(Bpin)邻苯二甲腈（1）和 3,5-双（Bpin）邻苯二甲腈（2），它们是合成功能化酞菁的潜在分歧中间体。为了说明 2 的用途，我们已经制备了一系列 3,5-双芳基邻苯二甲腈，它们可以进一步进行空间位阻控制的区域选择性环三聚化反应，得到以前未知的 C4h 1,3,8,10,15,17,22,24-八芳基酞菁。
