Journal ArticleMechanistic insight into rapid oxygen-atom transfer from a calix-functionalized polyoxovanadateFertig, Alex. A.; Cooney, Shannon E.; Meyer, Rachel L.; Brennessel, William W.; Matson, Ellen M.We report accelerated rates of oxygen-atom transfer from a polyoxovanadate–alkoxide cluster following functionalization with a 4- tert butylcalix[4]arene ligand. Incorporation of this electron withdrawing ligand modifies the electronics of the metal oxide core, favoring a mechanism in which the rate of oxygen-atom transfer is limited by outer-sphere electron transfer.2022-05-1710337038Chemical Communications58406004 to 60071359-7345https://doi.org/10.1039/D2CC01228F1653195National Science Foundation
