硫脲双环衍生物的合成和硝化

SYNTHESIS AND NITRATION OF BICYCLIC THIOUREA DERIVATIVES

硫脲与乙二醛、１，１，３，３四乙氧基丙烷及４，５二羟基咪唑烷酮在不同条件下进行缩合反应时，得到硫脲及异硫脲两种双环衍生物，再进一步硝化，分别生成脲环硝胺及异硫脲多硝基化合物。通过实验。

Condensation of thiourea with glyoxal, 4,5dihydroxy imidazolidine and 1,1,3,3tetraethoxypropane gave bicyclic thiourea and isothiourea derivatives, respectively,which were nitrated to form their corresponding polynitrocompounds.
