Pagination or Media Count:
Hypophosphorous acid reduction of chloromethylarsonic acid produces the novel cyclopolyarsine, pentakischloromethylcyclopentaarsine PCCA. PCCA possesses a greater thermal and oxidative stability than other cyclopolyarsines previously studied. The dynamic pmr properties of PCCA are interpreted as a combination of a low-energy limited pseudorotational motion and a higher-energy As-atom inversional process. An alternative to ground-state d-orbital participation in the interpretation of the electronic spectra is offered.
