with benzyltriphenylphosphonium salts in the presense of n-BuLi gave 2,7-di-tert-butyl-4-(phenylethenyl)pyrenes, from which naphthalene condensed aromatic compounds, 2,7-di-tert-butyl-dibenzo[ij, no]tetraphenes, were obtained by photo-induced cyclisation in the presense of iodine.
在正丁基锂的存在下,2,7-二叔丁基芘-4-甲醛与苄基三苯基鏻盐的 Wittig 反应得到 2,7-二叔丁基-4-(苯基乙烯基)芘,从中可以得到萘稠合的芳香族化合物, 2,7-二-叔丁基-二苯并[ij, no]四苯是在碘存在下通过光诱导环化获得的。
