The addition of silylboronic esters to pyridine takes place in toluene at 50 °C in the presence of a palladium catalyst to give N-boryl-4-silyl-1,4- dihydropyridines in high yield. The regioselective 1,4-silaboration also proceeds in the reaction of 2-picoline and 3-substituted pyridines, whereas 4-substituted pyridines undergo 1,2-silaboration to give N-boryl-2-silyl-1,2- dihydropyridines regioselectively.

Reductive cyclization of 1-(2,4-dinitrophenyl)-3-methyl-4-dimethylphenylsilylpyridinium chloride by the action of phenylhydrazine or hydrogen in the presence of Pd/C gave, for the first time, 7-nitro(amino)-3-dimethylphenylsilylpyrido[1,2-a]benzimidazoles. 1996 Plenum Publishing Corporation.

3-Methyl-4-dimethylphenylsilylpyridine and 3-methyl-4-methyldiphenylsilylpyridine, which were obtained from β-picoline and dimethylphenylchlorosilane and methyldiphenylchlorosilane, respectively, were coverted by catalytic dehydrocyclization to 9,9-dimeth
