| Abstract: | The 2-electron reduction of the unsaturated Pd3(dppm)3(CO)2+ cluster ([Pd3]2+) affords the highly reactive neutral cluster [Pd3]0, which reacts with nitrosobenzene (PhNO) yielding the organic azoxybenzene product (PhN(O)NPh) via the formation of “triplet” nitrene “PhN”. The formation of [Pd3(μ3-O)] as a possible (relatively unstable) intermediate is also postulated based on MALDI-TOF findings, but not formally demonstrated. Concurrently, no reaction between [Pd3]0 and OPPh3 occurs.
