A study of the photochemistry of vinylidine dihalides 1 and 2 and vinylhalides 4 and 5 revealed some interesting differences in their photobehaviour. This study led to uncover an important constraint in the generation of vinyl cations from certain α-unsubstituted vinyl halides such as 4.

(Z)-(3,3-Dimethylbicyclo[2.2.1]hept-2-ylidene)methyllithium can be readily generated by treatment of (Z)-3-bromomethylene-2,2-dimethylbicyclo[2.2.1]heptane with tert-butyl-lithium. At -75°C, the organometallic intermediate is configurationally stable and reacts with a variety of electrophiles under stereochemical retention.
