A nonstandard method of carbene generation is provided by reaction of 1 with AgBF 4 to give the transient metalladiphosphanylcarbene 2 . This unique dicationic singlet carbene can be trapped with bases (pyridine (Py) for example, see scheme) showing its electrophilic character, which is also confirmed by DFT calculations.
