Abstract

The reaction of butyryl chloride with ethynylbenzene in the presence of AlCl₃ afforded a mixture of the Z/E-isomers of 1-chloro-2-phenylhex-1-en-3-one. 1,2-Diphenylethyne under these conditions gave a novel polycarbocycle core, 6aH-benzo[a]fluorene. The chemical structure of 11-chloro-5,6-diphenyl-6a-propyl-6aH-benzo[a]fluorene was established by means of IE-MS, ¹H, ¹³C NMR, COSY, HSQC, HMBC, and 2D INADEQUATE technique.

6aH-苯并[α]芴：丁酰氯与1,2-二苯基乙炔反应意外产物的NMR证据。

丁酰氯与乙炔苯在AlCl3存在下的反应得到1-氯-2-苯基己-1-烯-3-酮的Z/E异构体的混合物。1,2-二苯基乙炔在这些条件下得到了新的聚碳环核6aH-苯并[a]芴。利用IE-MS、1H、13C NMR、COSY、HSQC、HMBC和2D INADEQUATE等方法，建立了11-氯-5,6-二苯基-6a-丙基-6aH-苯并[a]芴的化学结构。

期刊介绍： MRC is devoted to the rapid publication of papers which are concerned with the development of magnetic resonance techniques, or in which the application of such techniques plays a pivotal part. Contributions from scientists working in all areas of NMR, ESR and NQR are invited, and papers describing applications in all branches of chemistry, structural biology and materials chemistry are published. The journal is of particular interest not only to scientists working in academic research, but also those working in commercial organisations who need to keep up-to-date with the latest practical applications of magnetic resonance techniques.
