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.
