An Efficient Route to New 1,2,4,3-Triazaphosphole-3-Oxide Derivatives

Abstract

The condensation of hexamethylphosphorotriamide and bis-(dimethylamino) methylphosphonate with amidrazones 1 constitutes a new route to the synthesis of 1,2,4,3-triazaphosphole-3-oxide derivatives 3. Structures of all the synthesized compounds have been established by NMR (¹H, ¹³C, ³¹P) and IR spectroscopy, as well as by elemental analysis and MS spectral data for some products.

Keywords:

• Amidrazones
• bis-(dimethylamino) methylphosphonate
• hexamethylphosphorotriamide
• triazaphosphole
