- 中文摘要: 1,3-Diphenyl-5-imino-2-imidazolidinone-4-thione (II) was treated with diazomethanes to give (III-V). Interaction of (II) with amino compounds furnished the corresponding 4-substituted imino derivatives. Imidazoquinoxaline derivatives were obtained through interaction of (II) with o-phenylenediamines. Condensation of (II) with hydrazines afforded the hydrazones (IX,Xa,b). Semicarbazone and thiosemicarbazone derivatives were prepared from the reaction of (IX) with isocyanates and isothiocyanates . Again(II) was allowed to react with n-butylmagnesium bromide and HgCl/sub 2/ to give (XIII) and (XIV) respectively.
