摘要:
In the thermolysis of the silaterazolines sitatetrazoline (Bu2Si)-Bu-t=N-SiCl'Bu-2 center dot (Bu3SiN3)-Bu-t the silanimine (Bu2Si)-Bu-t=N-(SiClBu2)-Bu-t and the silyl azide (Bu3SiN3)-Bu-t are formed quantitatively. The silanimme (Bu2Si)-Bu-t=N-(SiClBu2)-Bu-t has been trapped with Et3NHF, Me3NHCl, water, 1-butene, 2,3-dimethyl-1,3-butadiene, isobutene, methylvinyl ether, and (Bu2SiCIN3)-Bu-t. The structure of the disiloxane (Bu-t(2)-SiCl-NH-(SiBu2)-Bu-t)(2)O kand of the bis(di-tert-butylchlorsilyl)-substituted silatetrazoline (Bu2Si)-Bu-t=N-SiCl(t)Bu(2)center dot(t)Bu(2)SiCIN(3) has been determined by X-ray structure analysis.
