- 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.
