Asymmetric synthesis and configurational stability of C2-symmetric hexacoordinated phosphate anions (TARPHATS) with predetermined chirality from tartrate esters
C2-Symmetric TARPHAT anions 5 made of a central Pv atom, one tartrato (=dialkyl 2,3-di(hydroxy-KappaO)butanedioato(2-)), and two tetrachloropyrocatecholato (=3,4,5,6-tetrachlorobenzene-1,2-diolato(2-)-KappaO,KappaO?) ligands can be easily prepared in decent to high yields (50-86%) as their dimethylammonium salt by using a one-pot process and simple commercially available starting materials. The presence of the chiral tartrato ligands (usually (2R,3R)) leads to the formation of diastereoisomeric anions ((Delta,2R,3R)/(Lambda,2R,3R)). Decent to good control by the chiral ligands-under equilibration conditions-over the Lambda or Delta configuration of the adducts was observed (d.r. 84:16 in CHCl3 for the di(tert-butyl) tartrate derivative), the selectivity depending on the nature of the ester chains as well as on the solvent.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application In Synthesis of Tris(dimethylamino)phosphine
