Preliminary results in- dicate that HMPA may enhance the reducing ability as well as prohibit the nucleophicility of allylSmBr, thus mak- ing allylSmBr/HMPA as a promising single-electron transfer （SET） reagent.展开更多

In the present paper we wish to present the synthesis and polymerization of 3-acrylato-4-oxo-3, 4-dihydro-1, 2, 3-benzotriazines as new bioactive monomers and polymers which have not been previously reported.展开更多
