Isobutylene → HCID 54188175, compound

Participants

Reaction Steps

In a flask equipped with a dry-ice-acetone reflux condenser were placed 23.9 grams of 5-chloro-3-methyl-3-pentenyl benzoate, 5.6 grams of isobutene and 100ml of 1,2-dichloroethane. To the mixture in the flask was added dropwise a catalyst solution consisting of 1 ml of tin tetrachloride (=stannic chloride) and 0.5ml of ethanol while stirring and cooling the system in an ice-water bath. The system was reacted for two hours with cooling and stirring, and then the reaction was stopped by adding 100ml of water to the system. The reaction mixture was further treated in the same manner as in Example 11, whereby 14.5 grams of 7-chloro-3,7-dimethyl-3-octenyl benzoate was obtained.
