Аннотация: Tetraalkyl-substituted pyrazines were obtained by the multicomponent reaction of aliphatic linear nitriles with EtAlCl₂ in the presence of Mg and Cp₂TiCl₂ catalyst in 60–91% yields. The same processing of isobutyronitrile gave 2,4,5-triisopropyl-1H-imidazole in 56% yield.

Ключевые слова: metal complex catalysis, dichlorobis(η⁵-cyclopentadienyl)titanium, ethylaluminum dichloride, nitriles, pyrazines, imidazoles.
