Halo complexes chloro fluoro

The treatment of o-bis(dimethylchlorostannyl)benzene 188 with fluoride or chloride ions gave in high yield a variety of /i-halo bis(stannyl)-containing complexes shown in Equation (12) <19980M5858>. The reaction is selective toward fluoride ions. Indeed, reaction of the starting complex 188 with fluoride ions leads only to the formation of the /i-fluoro product, while the /i-chloro product has not been detected. 

Chroraium(IV) complexes, 701, 927 alkoxides, 928 alkyls, 928 amides, 930 chloro, 927 cyano, 927 fluoro, 927 halo, 927 peroxo, 945 porphyrins, 916...
