The second problem in the addition of 1,1-dichlorodifluoroethylene to 1,3-butadiene is regiospecificity. Carbon 1 of 1,3-butadiene may become attached either to the carbon holding two chlorines or to the carbon with two fluorines. The cycloaddition of fluorinated alkenes is usually not a concerted four-center reaction in which the bonds are formed simultaneously or nearly so. Instead, the reaction is a stepwise biradical process in which the first step is formation of a free-radical intermediate with a single electron at that end of the double bond that can better accomodate it. That happens at the carbon linked to two chlorine atoms. Thus, a biradical is formed that cyclizes to form 2,2-dichloro-l,l-difluoro-3-vinylcyclobutane M [118, 119, 720]. 

Potassium salts of a set of heterocycles with different basicities, including imidazole, 2-methylebenzimidazle, 3,5-dimethylpyrazole, 1,2,4-triazole, andbenzo-triazole, were chosen for reactions with tetrafluoroethylene, chlorotiiiluoroethylene, and 1,2-dichlorodifluoroethylene (Fig. 3.102). Reactions with tetrafluoroethylene gave only A-tetrafluoroethyl derivatives, products of addition. (The reaction with the...
