Abstract

Isomeric cyclodiphosphazane selenides, R(X)P(NBu^t)₂P(Y)R (R = OMe or NMe₂, X = Se, Y = lone pair; R = OMe or NMe₂, X = Y = Se) display large differences (34–122 ppm) in ⁷⁷Se chemical shift. The ⁷⁷Se shifts of these and related amino derivatives are well to low field of the ⁷⁷Se shifts of analogous acyclic phosphorus selenides.
