Fujdaia. K. L Tilley. T. D. New vanadium tris(terf-butoxy)siioxy complexes and their thermolytic conversions to vanadia-silica materials. Chem. Mater. 2002. 14, 1376-13B4. [Pg.367]

Thermolytic conversions of aromatic pyridines into pyrazines have been reported, albeit in minute yield. Thus vacuum pyrolysis of 4-dichloroamino-2,3,5,6-tetrafluoropyridine (69) at 550°C gave at least 12 products in which 2,3,5,6-tetrafluoropyrazine (70) could be identified 1320 and flow thermolysis of 4-azido-2,3,5,6-tetrafluoropyridine in nitrogen at 300°C gave l,2-difluoro-l,2-bis(3,5,6-trifluoropyrazin-2-yl)ethylene (71), isolated in 0.1% yield.1322... [Pg.57]

Thermolysis. Note The observation that an alkoxypyrazine can undergo thermolytic conversion into a pyrazinone plus an alkene1699 has been studied kinetically59,64,238 but does not appear to have been developed as a preparative procedure. For example, 2-ethoxypyrazine (24) gave 2(l//)-pyrazinone (25) plus ethylene (26).238... [Pg.194]
