Why so different? The comparison of the reaction of “bare” [P 4 O 10 ] .+ and [V 4 O 10 ] .+ with ethene by mass‐spectrometric and computational studies permits insight into mechanistic aspects of the competition between CH bond activation and oxygen‐atom and electron transfers. Whereas [P 4 O 10 ] .+ reacts by homolytic CH bond cleavage and electron transfer, the isostructural [V 4 O 10 ] .+ shows only oxygen‐atom transfer (see picture).
