Structure and rearrangements of 3-Iso(thio,seleno)cyanato-1,2,3-triarylcyclopropenes
摘要:
A series of new fluctional 3-iso(thio,seleno)cyanato-1,2,3-triarylcyclopropenes was synthesized. The structure of compounds was proved by H-1 and C-13 NMR, IR, and mass spectra, and that of 3-(1,2,3-triphenylcyclopropenyl) isothiocycnate was confirmed by X-ray crystallography. In compounds under consideration by means of H-1 and C-13 NMR was discovered and investigated a fast reversible migration of isocyanato, isothiocyanato, and isoselenocyanato groups along the perimeter of the theree-membered ring proceeding according to the dissociation-recombination mechanism.
