Tris(triphenylphosphine)rhodium(I) chloride(CAT: R056611), commonly abbreviated as RhCl(PPh₃)₃, is a well-known organometallic complex featuring a rhodium(I) center coordinated to one chloride ion and three triphenylphosphine ligands. This bright yellow compound is extensively used as a homogeneous catalyst in organic synthesis, particularly in hydrogenation, hydroformylation, and C–C bond-forming reactions. Its defined geometry and tunable reactivity make it a cornerstone in transition metal catalysis and mechanistic studies. RhCl(PPh₃)₃ is ideal for developing selective catalytic processes in pharmaceutical and fine chemical industries.
