Abstract:

The structures of thirteen 5,10-dihydrophenophosphazine derivatives were elucidated by 1H, 13C and two-dimensional NMR. The 1H and 13C chemical shifts were assigned, and the coupling constants between 19P and 1H/13C were determined accurately. The factors affecting coupling constants were also investigated.

Key words: NMR, assignment, 5,10-dihydrophenophosphazine derivatives, coupling constant
