Abstract

The synthesis of several fluorinated cyclobutanes by cyclization of CFFCX~ olefins with themselves, and other olefins is reported. It appears that this cycloaddition takes place quite readily and easily only when X is halogen. The direction of addition of the unsymmetrical haloolefins can be rationalized and predicted by the assumption that in the productdetermining transition state, the diradical of the lowest energy is preferentially ...
