Abstract

The preparation of 7.7-dichlorobicyclo [4.1.0]heptane which is also known as 7,7-dichloronorcarane was done by reacting cyclohexene , chloroform and a base( 50% aqueous sodium hydroxide) with benzyl triethylammonium chloride. The latter being a water soluble phase transfer catalyst (PTC).reaction was performed at room temperature and was distilled at atmospheric pressure. The mechanism of action of the above mentioned PTC is described in the text along with the mechanism for the addition of a dichlorocarbene. The percentage yield obtained was 38.80%. This is considerably low due to an unfortunate spillage of the product at the stage of semi- micro distillation.



Introduction
Phase transfer catalysts (PCT) are used to catalyze reactions involving chemical species which are present in different phases. These types of reactions are known as a homogeneous two phase reactions and are usually very slow because the two primary reactants (in this case CHCl3 and NaOH)......
