In reaction of 5-aryl(hetaryl)tetrazoles with phenyl isocyanate under the conditions of microwave activation the corresponding 2-anilino-5-aryl(hetaryl)- 1,3,4-oxadiazoles formed in high yields. The application of the microwave activation fourfold reduced
15N NMR study of substituted 2-(phenylamino)-5-phenyl-1,3,4- oxadiazoles
Gierczyk, Blazej,Nowak-Wydra, Barbara,Grajewski, Jakub,Zalas, Maciej
, p. 123 - 127 (2007/10/03)
Substituted 2-(phenylamino)-5-phenyl-1,3,4-oxadiazoles were studied by 15N NMR spectroscopy. All signals were assigned on the basis of HMQC and HMBC experiments. Chemical shifts values were correlated with empirical Hammett parameters as well a
