Abstract

Abstract: The ¹³C NMR speatral parameters of 2-Thiono-2-diethylamino-3-substitutedbenzoyl (phenylsulfonyl)-1,3,2-oxazaphospholidines have been determined in CDCl₃ solutions. For the first time a two-bond temperature-dependent ¹³C-³¹P nuclear spin coupling was observed for the N-diethylamino carbon in O-substituted benzoy1-1,3,2-oxazaphospholidines, because the steroconformation of the carbonyl group and the benzene ring varied with temperature.

Key words: 1,3,2-oxazaphospholidines, ¹³C NMR, ²J_PC coupling constant of PNC bond
