The substitution reactions of [Rh(COD)2][BArF4] with PNP and PONOP pincer ligands 2,6-bis(di-tert-butylphosphinomethyl)pyridine and 2,6-bis(di-tert-butylphosphinito)pyridine in the weakly coordinating solvent 1,2-F2C6H4 are shown to be an operationally simple method for the generation of reactive formally 14 VE rhodium(i) adducts in solution. Application of this methodology enables synthesis of known adducts of CO, N2, H2, previously unknown water complexes, and novel vinylidene derivatives [Rh(pincer)(CCHR)][BArF4] (R = tBu, 3,5-tBu2C6H3), through reversible reactions with terminal alkynes.

An expedient new route to the cationic [(PNPtBu)Rh(L)] + metal fragments (PNPtBu = κ3-NC 5H3-2,6-(CH2P tBu2) 2; L = CO, acetone, ethene, MeCN, N2) by the synthesis of, then substitution of PCy3 in, [(PNPtBu)Rh(PCy 3)][BArF4] is reported. This synthetic route also allows for the synthesis of the new dihydrogen complex [(PNP tBu)Rh(H2)][BArF4]. [(PNP R)Rh(PCy3)][BArF4] (R= Ph, Cy, Mes) are also reported, in which the PCy3 ligand is more tightly bound to the metal center.
