Bis trichloro

Another approach to the benzo-1,3-ditellurole 54 is founded in the reaction of bis(o-trimethylsilyl)benzene with the easily accessible bis(trichloro-telluro)methane (85JA675). The l,l,3,3-tetrachlorobenzo-l,3-ditellurole 56 is reduced to 54, yield 18-20% (91MI1). [Pg.75]

Binuclear silicon chelates (55a,c,g,j) were prepared from 1,2-bis(trichloro-silyl)ethane and Af-dimethylamino-O-trimethylsilylimidates (la,c,g,j) in high yields.69 The hexacoordination of these complexes is evident from a crystal structure analysis obtained for 55c (Fig. 23), as well as from their...

The trichloromethyl group in s-triazines is sufficiently reactive to he displaced by ammonia, amines, or alkoxides even if two deactivating groups have already been introduced. In contrast, under much more vigorous conditions benzotrichloride and 2,6-bis(trichloro-methyl)pyridine are unreactive towards ammonia in dimethyl-formamide (2 hr, 165°). Tris-amination of 2,4,6-tris-(trichloro-methyl)-s-triazine is complete in aprotic, but not in protic, solvents. [Pg.203]

An large number of pyrazines were subjected to X-ray crystallographic analysis.
