(9-anthryl)diphenylmethyl hexachloroantimonate (1) with nucleophiles gave mainly the quinoidal products by attack on the 10-position of the anthracene ring, suggesting the existence of a strong interaction of the two phenyl rings with the hydrogens at the 1- and 8-positions of the anthracene ring. Compound (1) is propellorshaped, and thus approach by the nucleophile to the benzylic site is difficult. For the reactions
(9-蒽基)二苯基甲基六氯锑酸酯(1)与亲核试剂的反应主要是通过攻击蒽环的10位而得到的醌类产物,表明两个苯环与1处的氢存在强相互作用。 -和蒽环的8位。化合物(1)是螺旋桨形的,因此亲核试剂难以接近苄基位点。对于9-二苯基亚甲基-10-氯-9,10-二氢蒽的反应,获得的数据表明亲核试剂接近蒽环的10位的方法比(1)的情况更受阻碍。通过用苯基取代(1)的10-氢,观察到亲核试剂在位置10上的进攻显着延迟。
