SYNTHESIS OF 1,3-SELENAZETIDINE DERIVATIVES FROM IMINES AND THIOCARBAMOYL ISOSELENOCYANATE

摘要

Reactions of thiocarbamoyl isoselenocyanate with imines afforded 1,3-selenazetidines under reflux conditions. We could confirm the structure using significant difference of chemical shifts between selenazetidines and selenoureas including cyclic selenoureas in ~(77)Se NMR spectra.
