在末端或内炔（3）和2，6-二叔丁基-4-甲基吡啶的存在下，用四（五氟苯基）硼酸三苯甲基酯（TPFPB）处理二烷基苄基硅烷（1），得到相应的1，2-二氢-2-硅萘衍生物（4），产率为34-82%。
Treatment of dialkylbenzylsilane (1) with trityl tetrakis(pentafluorophenyl) borate (TPFPB) in the presence of terminal or internal alkynes (3) and 2,6-di-tert-butyl-4-methylpyridine gave the corresponding 1,2-dihydro-2-silanaphthalene derivatives (4) in 34-82% yields.
