This work describes a base-mediated borylsilylation of benzylic ammonium salts to synthesize geminal silylboronates bearing benzylic proton under mild reaction conditions. Deaminative silylation of aryl ammonium salts was also achieved in the presence of

Polycations of two oligoanilines based on Wurster's blue, N,N',N-tris[4-(dimethylamino)phenyl]-N,N',N-trimethyl1,3,5-benzenetriamine (2) and N,N'-bis(3-{N-[4-(dimethylamino)phenyl]-N-methylamino}phenyl)-N,N'-dimethyl- pphenylenediamine (3), have been generated efficiently by a stepwise oxidation procedure, Their redox behavior was characterized in terms of the embedded p-phenylenediamine (PD) units and their intramolecular connectivity, EPR analysis of the oxidized 2 and 3 species revealed the existence of high-spin species in solution. It was found that spin multiplicities of the dominant polycationic species of 2 and 3 formed by 3 equiv, of oxidant can be assigned to quartet: and doublet states, respectively on the basis of pulsed EPR spectroscopy, These results demonstrate that the intramolecular connectivity between the spin-containing units decisively influences the spin preference of the multispin systems based on oligoanilines.
