The one-pot reaction of the alcohol adducts F3CP(H)CF20R of perfluoro-2-phosphapropene with secondary amines in a 1 : 3 molar ratio affords the stable phosphaalkenes F3CP=C(OR)NR2 ( R = Me, Et) 1-4 in yields of 58%. NMR and He(Z) PE spectroscopic investigations show that the lone pair electrons on n
## Abstract A selection of mono‐ and pseudo __ortho__ di‐substituted octafluoro[2.2]paracyclophane derivatives were analyzed using ^19^F‐^1^H HOESY, ^1^H COSY and ^19^F COSY techniques. This resulted in the unambiguous assignment of the ^19^F and ^1^H NMR resonances, and also revealed interesting s
