二苯基乙炔在四氢呋喃溶液中与σ-三苯基铬作用,除获得Zeiss等报告的产物1,2,3,4-四苯基蓁和六苯基苯外,还分离得9,10-二苯基菲、四苯基乙烯和对三联苯.在乙醚溶液中进行的相同反应也得上述各种产物.由于9,10-二苯基菲的获得,我们对Zeiss机理提供有力的补充的说明:即σ-三苯基铬四氢呋喃絡合物中的四氢呋喃配位体逐步被二苯基乙炔置换,而与铬结合的苯基参加缩合反应,因而形成菲、萘、苯衍生物.至于四苯基乙烯的生成机理,目前尚难肯定.σ-三(邻甲苯基)铬四氢呋喃絡合物与二苯基乙炔作用生成1,2-二苯基-1,2-二(邻甲苯基)乙烯.

The reaction of diphenylacetylene with σ-triphenyl-chromium tetrahydrofuranate in tetrahydrofuran gave a series of aromatic compounds:1,2,3,4-tetraphenylnaphthalene,hexaphenylbenzene,9,10-diphenylphenanthrene,tetraphenylethylene,and p-terphenyl,among which only the former two out in ether gave the same have been reported by zeiss et al.The same reaction carried products.
