Unsaturated Radicals Bearing Fluorine Atoms on the Chain

Unsaturated Radicals Bearing Fluorine Atoms on the Chain 

Nevertheless, these results appear attractive and it may be hoped that further studies will permit one to propose new synthetic methods, particularly in the area of small rings. One recent example may be found in the intricate mechanism ending with a Cy5/Cy6 cyclization recently proposed to rationalize some of the products obtained in the reaction of CF2=CCl2 with alkyl Grignard reagents.
