Isomerisation, reactivity and coordination chemistry of a new hybrid, multi-functional phosphazane

摘要

The unsymmetric P-III/P-V cyclodiphosphazane framework [(S-)(H) P(mu-(NBu)-Bu-t)(2)(PNHBu)-Bu-t] (2) provides entry into the mixed chalgogenide dianion [(S)P(mu-(NBu)-Bu-t)(2)P(Se)(NBu)-Bu-t](2-), and unique insight into the mechanisms of cis/trans isomerism in phosph(III)- and phosph(v)-azanes.
