WebGeneral Procedure for Catalytic Asymmetric Hydrogenation of Enamides: In a glovebox, the Rh- phosphine complex was made in situ by mixing Rh(COD)2PF6(3.7 mg, 0.008 mmol) and 1 (0.8 mL of 10mg/mL ligand in toluene, 0.012 mmol) in 19.2 mL of CH2Cl2. The mixture was stirred for 30 min. WebA straightforward synthesis of the tetradentate phospholane ligand 1 is reported. The 2 : 1 [M : L] reaction of 1 with [AuCl(tht)] (tht = tetrahydrothiophene) resulted in the 4 : 2 [M : L] supramolecular coordination complex 2 where two ligands 1 are bridging four gold(I) cations.The formation of 2 can be rationalised via a geometrical analysis of the ligand.
