Recent work out of the group of Martin Smith at Loughborough University presents the possibility of cleaving a P-P bond at an iridium(III) metal centre by adding an AuCl unit.
Computations elucidate the underlying energetics and rationalise the results using the natural bond orbitals (NBO) approach.
