ENANTIOSELECTIVE SYNTHESIS OF SECONDARY ALCOHOLS IN THE PRESENCE OF CHIRAL LIGANDS

The synthesis of two S-proline derivatives is described together with their use as chiral ligands for lithium in reactions of n-butyllithium with benzaldehyde to give 1-phenyl-1-pentanol with moderate optical purity.The presence of lithium salts in the reaction mixture causes a decrease in asymmetric induction.

Molybdenum-95 nuclear magnetic resonance studies on molybdenum carbonyl complexes of isonitriles and amines

The 95Mo NMR spectra of 28 molybdenum carbonyl complexes of isonitriles and amines are reported.Within similar classes of complexes excellent correlation is found between 95Mo chemical shifts and ligand ?-acceptor ability and, more importantly, complex structures.Application to the analysis of diastereomeric complexes is reported.From analysis of linewidths and relaxation behavior, the surprising result is found that 95Mo linewidths in isonitrile complexes are not due to coupling to the electric field gradient, but to scalar coupling between the 95Mo and 14N nucleiwhich, in turn, is inversely proportional to the substitution number n in complexes Mo(CO)6-n(CNR)n.A dependence of chemical shift on temperature of 0.3 ppm/deg C is found for Mo(CO)6.
