The electron-transfer catalysed substitution of PPh3 for CO on Ru3(CO)12 mediated by dibenzoylethylene was studied using a factorial design experiment. Within the range of conditions investigated, the efficiency of the reaction was affected exclusively by a two-factor interaction between the Ru3(CO)12 and PPh3 concentrations. Maximum turnover numbers were achieved only when both of these concentrations were at their high levels. The dibenzoylethylene concentration and the current had no significant effect on efficiency. Other phosphines (PR3, R = Me and/or Ph or Bu), P(OMe)3 and Bu1NC show similar reactivity.
