Trapped! Transient electrophilic phosphinidenes [R-P=W(CO)5] have emerged as versatile intermediates that are highly valuable in the synthesis of a plethora of organophosphorus compounds, nevertheless their existence has never been unequivocally established. By employing electrospray ionisation tandem mass spectrometry (ESI-MS/MS), this low-valent species has now been detected and its gasphase reactivity perfectly matches the well-established solution-phase data.
