Notes:
(Di-tert1-butylfluorosilyl)hydrazine, a Building Block for Structure-Isomeric N,N- and N,N′1-Bis(silyl)hydrazinesDi-tert1-butyldifluorosilane reacts with monolithiated hydrazine to give the stable monosilylated hydrazine 1 and the six-membered ring 2. The bis(fluorosilyl)hydrazine 3 is formed in a condensation reaction by heating 1 at 220°C. HCl elimination between 1 and chlorosilanes leads to the N,N′1-disubstituted hydrazines 4 and 5. An N,N′1-bis(silyl)hydrazine 6 is obtained in the reaction of lithiated 1 with difluorodiisopropylsilane while an N,N1-bis(silyl)hydrazine 7 is formed with tert1-butyltrifluorosilane. Structural isomerism (8-11) is observed in reactions of lithiated 1 with [(trifluorosilyl)amino]silanes.
