The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

In
benzene;
byproducts: SnCl2; Under N2; addn. of 1,3-di-t-butyl-2,2-dimethyl-1,3,2,4λ2-diazasilastannetidine to a soln. of 1,2-dichloro-1,2-diphenylethane in benzene (stirring). Refluxed for 3 h at 80°C.; The spiro-tetraazastannane is separated by sublimation (110 °C, 0.01 Torr). Identified by H-NMR.;

In
benzene;
Addn. of a soln. of 1,2-dibromocyclohexane in benzene to a soln. of 1,3-di-t-butyl-2,2-dimethyl-1,3,2,4-diazasilastannetidine; soln. stirred for 4 h at 20°C under N2 (the colour changes from orange to light yellow). Pptn. of tin(II) bromide.; The solvent, unreacted 1,2-dibromocyclohexane, and cyclohexene are evapd.. The spiro-tetraazastannane and 1,3-di-t-butyl-2,2-dimethyl-4,4-dibromo-1,3,2,4-diazasilastannetedine are sepd. by fractional sublimation.;
