The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

Bicyclic compounds exo,exo-α-P4Se3X2 and exo,exo-α-P4Se3XI (X = CN, NMePh or NPri2) and endo,exo-α-P4Se3(CN)2 have been made in solution and their 31P and 77Se NMR spectra completely analysed. Ab initio calculations of 31P and 77Se NMR shieldings in exo,exo- and endo,exo-α-P4Se3(CN)2 and in exo,exo-α-P4Se3(CN)I confirmed these assignments. In an unsymmetric compound exo,exo-α-P4Se3XI the twelve 31P-77Se NMR coupling constants have values related to those in the corresponding symmetric compounds exo,exo-α-P4Se3X2 and exo,exo-α-P4Se3I2 by simple rules, useful for predicting couplings in exo,exo-α-P4Se3X2 when the spectra of exo,exo-α-P4Se3XI and exo,exo-α-P4Se3I2 have already been analysed.
