Abstract: Using anhydrous hydrazine and trimethyl chlorosilane as raw materials,1,2-bis(trimethylsilyl) hydrazine was synthesized with the yield of 83%.Then through activation of butyllithium,tris(trimethylsilyl) hydrazine were synthesized with the total yield of 75%.Further through solvothermal reaction of lithium-tris(trimethylsilyl)hydrazine and trimethyl chlorosilane,tetra(trimethylsilyl) hydrazine were synthesized with the total yield of 34%.Their structures were characterized by means of NMR,IR,MS and elemental analysis.The self-condensation reaction of mono (trimethylsilyl) hydrazine and rearrangement reaction of bis(trimethylsilyl) hydrazine induced by heat action were analyzed.Results show that these reactions are caused by the inter-and intra-mo-lecular migration of trimethylsilyl group on hydrazine,and isomerization of bis(trimethylsilyl) hydrazine could occur obove 75 ℃.
