Synthesis of Rh(III) thiophosphinito pincer hydrido complexes by base-free C–H bond activation at room temperature

Rhodium(III) thiophosphinito pincer hydrido complexes were synthesised by C–H activation under exceptionally mild conditions at room temperature without additional base or irradiation and fully characterised by multinuclear NMR spectroscopy and X-ray crystallography. C–H activation under these mild conditions contrasts with the reactivity of related systems with POCOP ligands.
