Abstract

Electron-rich organosilicon compounds, such as 1, 4-bis (trimethylsilyl)-1, 4-diaza-2, 5- cyclohexadiene (2a), 2, 5-dimethyl-1, 4-bis (trimethylsilyl)-1, 4-diaza-2, 5-cyclohexadiene (2b), 2, 3, 5, 6-tetramethyl-1, 4-bis (trimethylsilyl)-1, 4-diaza-2, 5-cyclohexadiene (2c), and 1, 1′-bis (trimethylsilyl)-1, 1′-dihydro-4, 4′-bipyridine (4), served as versatile reducing reagents of group 4–6 metal chloride complexes, such as Cp2TiCl2, Cp* 2TiCl2 (Cp*= η5- ...
