Stepwise replacement of O in 1,3‐dioxa‐2‐phospha(V)‐cyclohexanes (or related ring systems) by NR (R=H or Me) leads to an increase in the stability of the hetero‐ring ions produced under electron impact conditions. In the case of the 2‐phenoxy derivatives, there is also an increased abundance of [MPhO] + or [MPhOH] + ions, and, for the 2‐sulphides, a reduction in the abundance of [M‐S] +˙ and [M‐SH] + ions, with a concurrent increase in that of [M‐PhS] + ions. Such trends have been correlated with ultraviolet photoelectron spectral data on a qualitative basis.
