Dehydrocondensation of triorganosilanes with piperazine and some aliphatic amines in the presence of potassium metal
- 30 Downloads
Reaction of CH3(C6H5)2SiH with C4H9NH2 in the presence of potassium metal gives, instead of the expected CH3(C6H5)2SiNHC4H9, benzene, diphenyl, and what is apparently a hitherto unknown substituted cyclodisolazane. The Si-C6H5 bond is broken not only by alkali metals, but also by their amides. For the case of piperazine it is shown that heterocyclic diamines react considerably more readily with trialkylsilanes than do aliphatic secondary amines.
