Irradiation of 1,1-diarylcyclopropanes 4a-g, having substituents X and Y at the para positions of the aromatic rings, afforded 1,1-diarylpropenes 5a-g and 1-arylindans 6a-f.The rate constants of these (singlet state) reactions, determined from the reactan

The action of dimethyl sulphone-potassium hydroxide-t-butyl alcohol on carbon tetrachloride readily affords dichlorocarbene.In the presence of alkenes, gem-dichlorocyclopropanes are formed in moderate to high yields.The dichlorocarbene generated by this procedure adds stereospecifically to alkenes with retention of geometric configuration about the carbon-carbon double bond.Relative reactivities of alkenes towards the CCl4-derived dichlorocarbene parallel the nucleophilicities of the alkenes and indicate that free dichlorocarbene is probably involved.

The addition of dichlorocarbene to 1-phenyl-1,2-alkadienes takes place regioselectively at the most substituted multiple bond.On heating, the initial reaction products isomerize to the corresponding (dichloromethylene)cyclopropanes.
THERMAL TRANSFORMATIONS OF GEM-DIHALOGENODIPHENYLCYCLOPROPANES

When gem-dihalogenodiphenylcyclopropanes are heated, 2-halogenophenylindenes or diphenyl-2-halogeno-1,3-alkadienes are formed.The yields of the substituted indenes are increased in the presence of acidic catalysts, while the yield of the dienes is increas
