- Аннотация: Generation of Br-bridged complex of cobalt bis(1,2-dicarbollide) (8,8’--Br-3,3’-Co(1,2-C2B9H10)2) and its reactions with arenes and some nucleophiles were studied. Complex 8,8’--Br-3,3’-Co(1,2-C2B9H10)2 can be generated in situ by an action of 8-monobromo derivative of cobalt bis(1,2-dicarbollide) and AlX3 (X=Cl, Br) in different aromatic solvents. This unstable complex was characterized by 11B NMR technique for the first time. Its reactions with an appropriate arene led to [8-Br-8’-Ar-3,3’-Co(1,2-C2B9H10)2]- species even without an addition of activating Lewis base. Reactions of 8,8’--Br-3,3’-Co(1,2-C2B9H10)2 with S- and N-nucleophiles (thioxane, morpholine) in benzene afforded the corresponding charge compensated derivatives (8-Br-8’-Y-3,3’-Co(1,2-C2B9H10)2) as well as [8-Br-8’-Ar-3,3’-Co(1,2-C2B9H10)2]- species.
