摘　　要：标题化合物可由氰化亚铜催化下的苯基溴化镁与2-苯基-1-对甲苯砜基乙炔的碳镁化反应得到,并用1HNMR,IR和MS对其进行了表征.其晶体结构经单晶X-射线衍射法测定.晶体属单斜晶系,空间群P2(1)/c,晶胞参数:a=12.8256(6),b=5.8678(7),c=23.871(3) ;α=90°,β=105.360(3)°,γ=90°,V=1732.3(4) 3,T=293K,Z=4,Dc=1.282g·cm-1,μ=0.196mm-1,λ=0.71073 ,F(000)704,结构偏离因子R=0.0427,wR=0.0461,共收集到10150个独立衍射点,其中I>2σ(I)的可观测点为4060个.The title compound was synthesized by the carbomagnesiation of phenylmagnesium bromide and 2-phenyl-1-(p-tolylsulfonyl)ethyne. The title compound was characterized by^1H NMR,IR and MS. The single crystal structure was determined by X-ray diffraction analysis. Crystal crystallizes in monoclinic, space group P2(1)/c with unit cell parameters: a=12.8256(6),b=5.8678(7), c=23.871(3)?;α=90°,β=105.360(3)°,γ=90°, V=1732.3(4)?~3,T=293K, Z=4, Dc=1.282g·cm^(-1),μ=0.196mm^(-1), (λ=0.71073?, F(000)704. The final R=0.0427, wR=0.0461,10150 independent were collected, of which 4060 independent reflections with I>2σ(I) were used.
