摘要：

An expedient new route to the cationic [(PNPtBu)Rh(L)](+) metal fragments (PNPtBu = K-3-NC5H3-2,6-(CH2P Bu-t(2))(2); L = CO, acetone, ethene, MeCN, N-2) by the synthesis of, then substitution of PCy3 in, [(PNPtBu)Rh(PCy3)][BAr4F] is reported. This synthetic route also allows for the synthesis of the new dihydrogen complex [(PNPtBu)Rh(H-2)][BAr4F](center dot)[(PNPR)Rh(PCy3)][BAr4F] (R=Ph, Cy, Mes) are also reported, in which the PCy3 ligand is more tightly bound to the metal center.
