✦ Synopsis

We have re-examined' the addition of dichlorocarbene to tetraphenylcyclone and found a new product which is not derived from 1,2-cycloaddition to the carbon-carbon double bond.

Addition of dichlorocarbene, generated from chloroform and base under phase transfer conditions,2 to tetraphenylcyclone !, gave two products, $ and %, in addition to some unreacted starting material.
