Participants

Reaction Steps

5.6 g (20 mmoles) of 4-hydroxy-4-(2-methyl-phenyl)-4H-indeno[1,2-b]thiophene were dissolved in 40 ml of absolute benzene, and 34 ml of thionyl chloride were added. The mixture was heated under reflux for 5 hours. The reaction solution was then evaporated in vacuo, the oily residue was taken up in cyclohexane, the insoluble material was filtered off and the clear filtrate was evaporated again in vacuo. 6.1 g of crude 4-chloro-4-(2-methyl-phenyl)-4H-indeno[1,2-b]thiophene were obtained as a viscous oil, which was further reacted directly. ##STR11##
