Study on Bivalent Silicon Compounds(Ⅰ)Synthesize of 2,5-Ditertbutyl-1-sila-2,5-diaza-3-cyclopentenesilylene

用３０％乙二醛与叔丁基胺反应，生成双核乙二醛缩叔丁基胺西夫碱，在ＴＨＦ中，与锂、四氯化硅反应，生成１，１－二氯－２，５－二叔丁基－１－硅杂－２，５－二氮杂－３－环戊烯，再与金属钾反应，生成２，５－二叔丁基－１－硅杂－２，５－二氮杂－３－环戊烯硅烯，用元素分析和１Ｈ－ＮＭＲ（Ｃ６Ｄ６）作了鉴定．

Glyoxal react with tert-Butylamine to form 1, 4-Di-tert-butyl-diazabutadiene(Ⅰ).In THF,(Ⅰ)react with lithium and tetrachlorosilane to give 1,1-dichloro2, 5-ditertbutyl-1-slia-2, 5-diaza-3-cyclopenene (Ⅱ).2,5-ditertbutyl-1-sila 2, 5-diaza-3-cyclopentenesilylene was synthesized by reaction of Ⅱ with Potassium in THF and characterized by means of elemental analysis and 1H-NMR(C6D6).
