We report mechanistic insights into an iridium/nickel photocatalytic C-O cross-coupling reaction from time-resolved spectroscopic studies. Using transient absorption spectroscopy, energy transfer from an iridium photocatalyst to a catalytically relevant Ni(II)(aryl) acetate acceptor was observed Concentration-dependent lifetime measurements suggest the mechanism of the subsequent reductive elimination is a unimol. process occurring on the long-lived excited state of the Ni(II) complex. We envision that our study of the productive energy-transfer-mediated pathway would encourage the development of new excited-state reactivities in the field of metallaphotocatalysis that are enabled by light harvesting. In addition to this study using fac-Tris(2-phenylpyridine)iridium, there are many other studies that have used fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Product Details of 94928-86-6) was used in this study.
fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) belongs to pyridine. Pyridine is a relatively complex molecule and exhibits a number of different bands in IR spectra. Among others, the bands characterizing the ν8a and ν19b modes have been found to be sensitive to the coordination or protonation of the molecule. Note that the band that is diagnostic for the PyH+ ion at about 1545 cm− 1 (ν19b mode) does not overlap with any of the other bands.Product Details of 94928-86-6
