THE CHEMISTRY OF FUSED DICYCLOTRIAZAPHOSPHOLE I. THE SYNTHESIS AND CONFORMATION OF 2-SUBSTITUTED-3-DIALKYLAMINO- 5,6-DISUBSTITUTED THIAZOLO-2,3- DIHYDRO-1,2,4,3-TRIAZAPHOSPHOLES

Abstract

Twelve fused dicyclotriazaphosphole derivatives were synthesized by cyclocondensation reaction of 4,5-disubstituted-2-N′-substituted hydrazinothiazoles with P(NR₂)₃, CIP(NR₂)₂ and Cl₂PNR₂. The conformation of these new compounds were discussed as well on the basis of the spectral data of ¹H, ¹³C and ³¹P NMR, MS and of their reaction.

Key Words:
