The potassium graphite reduction of L:PCl3 leads to the formation of carbene-stabilized diphosphorus molecules, L:P-P:L, 1 (L: = :CN(2,6-Pri2C6H3)CH}2) and 2 (L: = :CN(2,4,6-Me3C6H2)CH}2), respectively. The nature of the bonding in 1 and 2 was delineated by DFT computations.

The lithiated N-heterocyclic carbene-phosphinidene adduct L':P-H (3; L': = :C[N(2,6-(Pr2C6H3)-C-i)](2)CMCLi-(THF)(3)}) unexpectedly resulted from the reaction of lithium metal with the carbene-stabilized diphosphorus species L:P-P:L (2: L: = :CN(2,6-(Pr2C6H3)-C-i)CH}(2)). Compound 2 was previously prepared by the potassium graphite reduction of L:PCl3 (1).

A bridging chloride anion between two electrophilic phosphorus centers was observed for the first time in the molecular structure of the novel P-P bonded cation [(L2P2Cl3)-P-DiPP]+ (2(+); L-DiPP = 1,3-bis(2,6-diisopropylphenyl)-imidazol-2-ylidene). Cation 2(+) is prepared by the reduction of the monophosphorus species [(LPCl2)-P-DiPP](+) (1(+)) with sodium. DFT calculations, AIM and mechanochemical (compliance constants) analyses are used to examine the bonding situation of this unusual species. The monochloro-substituted cation [(L2P2Cl)-P-DiPP](+) (3(+)) was likewise observed as a reduction product of 1(+).

afforded [(IPr)PP(IMes)] (4). The corresponding radical cation [(IPr)PP(IMes)]˙+ (5˙+) is isolated as [5]PF6 by reaction of 4 with ferrocenium hexafluorophosphate, whereas complexes containing the corresponding dication [(IPr)PP(IMes)]2+ (62+) can be isolated as the gallate and borate salts [6](GaCl4)2 and [6](BArF)2 by chloride abstraction from 3 with GaCl3 or sodium tetrakis[bis(3,5-trifluoromethyl)phenyl]borate
