The method for preparing 1,2,3,4,5,6,7,8-octamethyl-1,3,5,7,2,4,6,8-tetrazatetrasilocane is as follows:
First, n-butyllithium is reacted with liquid ammonia to produce lithium butylamine.
Then, lithium butylamine is reacted with tetramethylchlorosilane to generate 1,1,1,4, 4,4-hexamethyl -2,3,5,6-tetraazalkyl alkene.
Finally, through the ring shear reaction, 1,1,1,4, 4,4-hexamethyl-2, 3,5, the 6-tetraazoalkylalkene is converted to 1,2,3,4,5,6,7,8-octamethyl-1,3,5,7,2,4,6,8-tetrazatetrasilocane.
For safety information, this compound should be used with caution. It may be irritating to the eyes, skin and respiratory system. During use, personal protective equipment such as protective glasses, gloves and protective masks should be worn. If exposed to the compound, immediately flush the affected area with plenty of water and seek medical help. In addition, it should be stored in a sealed container, away from fire and oxidizing agents.
