Synthesis and reactivity of the first η6-rhodium(I) and η6-iridium(I) complexes of 2,6-bis(trimethylsilyl)phosphinines

It has been shown that 2 equiv. of 2,3,5,6-tetraphenylphosphinine (2) react with [Rh(COD)2][BF4] to yield the bis(η1-phosphinine)RhI complex 6, whose X-ray crystal structure is presented. On the other hand, 2,6-bis(trimethylsilyl)phosphinines 4 and 5 react with Rh+ and Ir+ precursors to yield the first (η6-phosphinine)RhI and -IrI complexes 7-10, and 11-12, respectively. The X-ray crystal structure of complex 8 is presented. Reaction of these η6-phosphinine complexes with water or ethanol yields the first (ν5-phosphacyclohexadieny1)RhI and -IrI complexes 13-17, resulting from the formal 1,1-addition of RO- and H+. DFT calculations comparing isoelectronic (η6-phosphinine)- and (η6-benzene)Fe0 and -RhI complexes allows the rationalization of the large difference in reactivity of these complexes.
