  摘要：

  Twenty one new thiophene-substituted 1,2,4-oxadiazo1-5(4H)-ones, 1,2,4-oxadiazol. 5(4H)-thiones, and 1,2,4-oxadiazin-5(6H)-ones were synthesized by the reaction of thiophene-ring substituted amidoximes with ethyl chloroformate, thiophosgene, and chloroacetylchloride, respectively. Their structure elucidation was performed by means of spectral measurements (IR, NMR, and MS) and physical data.

  Abstract Twenty-two new 3,4,5-trisubstituted 1,2,4,5-oxadiazaboroles were prepared by the cyclocondensation reaction of N-substituted thiophene, furan and pyridine carboxamidoximes with phenylboronic acid in refluxing toluene in good yields. The structures of the new oxadiazaboroles were elucidated by means of spectral measurements (IR, 1H, 13C, 11B NMR, MS, X-ray) and physical data (melting points

  摘要通过N-取代噻吩，呋喃和吡啶羧酰胺肟与苯基硼酸在回流甲苯中的缩合反应，制得了22个新的3,4,5-三取代的1,2,4,5-恶二氮杂硼烷。通过光谱测量（IR，1H，13C，11B NMR，MS，X射线）和物理数据（熔点，HRMS的元素组成）阐明了新的二氮杂硼硼烷的结构。
