Observed instability of bound pybox ligands towards acetate counterions

by Kazi, A. B.; Jones, G. D.; Vicic, D. A.

Reaction of Pd(OAC)(2) with bis(oxazolinyl)-pyridine (pybox) ligands led cleanly to products that Contained a ring-opened oxazoline ring. The transformations were formally the result of the attack of bound pybox ligands by acetate counterions, leading to acetate incorporation into the ring-opened products.
