(Di‐ tert 1‐butylfluorosilyl)hydrazine, a Building Block for Structure‐Isomeric N,N ‐ and N,N ′1‐Bis(silyl)hydrazines Di‐ tert 1‐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,N 1‐bis(silyl)hydrazine 7 is formed with tert 1‐butyltrifluorosilane. Structural isomerism ( 8–11 ) is observed in reactions of lithiated 1 with [(trifluorosilyl)amino]silanes.
