24. It is possible that a free boryl radical is reacting with a metal-bound alkane. This mechanism would involve both photochemical dissociation of CO to form a 16-electron complex, which would then bind alkane, and photochemical generation of free boryl radical, which would react with the alkane complex. Although this mechanism is consistent with our data, we suggest two simpler mechanisms.
