We describe a new class of inorganic polymeric materials featuring a main chain consisting of PV-O bonds and aryl side groups, which was obtained with >70 repeat units by ring-opening polymerization of cyclic phosphonates. This monomer-polymer system was found to be dynamic in solution enabling selective depolymerization under dilute conditions, which can be tuned by varying the substituents. The polymers show high thermal stability to weight loss and can be easily fabricated into self-standing thin films. Structural characterizations of the cyclic 6-and 12-membered ring precursors are also described.

(Chemical Equation Presented) By treatment with Woollins' reagent in toluene solution, carboxylic acids are converted to selenocarboxylic acids. The latter react in situ to provide new products of acid- or base-promoted substitution, addition, and amidation.
