(E/Z) stereoisomer assignment by 13C NMR in trifunctional phosphonate α-oximes and α-arylhdrazones
Abstract
13 NMR 1JPC coupling constants have predictive value in determining (E)vs.(Z) isomerism in oxophosphonoacetate α-oximes and α-hydrazones, and in distinguishing syn from anti phosphorus atoms in carbonyldiphosphonate α-hydrazones.
