Electron photoejection in carbanions. Progress report, July 1, 1979-June 30, 1980. [Photomethylation of triphenylmethyl anion in DMSO]
A systematic study was completed of the mechanism of photomethylation of triphenylmethyl anion in dimethyl sulfoxide. The mechanism includes the intervention of an electron transfer as the primary process, followed by a radical + carbanion reaction to lead to a radical anion, which ultimately restores its odd electron to the original triphenylmethyl radical formed. The photochemistry is extremely well behaved; the quantum yield for the process is concentration independent, no chain processes are initiated, and the photoproducts are concentration invariant. The quantum yield of disappearance of triphenylmethyl anion, which is constant from ca. 400 to 600 nm, shows a remarkable increase at shorter wavelengths, which may represent the onset of photoelectrons.
