Iridium-catalyzed direct tetraborylation of anthracene to give 1,3,5,7-tetrakis(Bpin)anthracene 5 was achieved by using a combination of [Ir(OMe)(COD)]2 and tmphen as the catalyst. Compound 5 was applied to the synthesis of 1,3,5,7-tetraarylanthracenes 7 as a new molecular entity. The latter showed long fluorescence lifetime in the solid state.
采用[Ir(OMe)(COD)]2和tmphen作为催化剂,成功实现了铱催化的蒽直接四硼化反应,生成1,3,5,7-四(Bpin)蒽化合物5。化合物5被应用于合成作为新分子实体的1,3,5,7-四芳基蒽7。后者在固态下表现出较长的荧光寿命。
