  Structural and ¹³C NMR Studies on Palladium MOP Compounds:  A New Weak C−Pd σ-Bond Plus MOP as a Bridging Diene Ligand

  摘要：

  A new set of Pd-MOP complexes (MOP = (S)-2-diarylphosphino-1,1'-binaphthyl) has been prepared. One of these, containing MeO-MOP (=2-(diphenylphosphino)-2'-methoxy-1,1'-binaphthyl), is shown to act as a chelating ligand with a naphthyl backbone diene bridging a Pd(I)-Pd(I) bond. This bonding mode exists in both the solid and solution states. A series of chloro-Pd(II)MOP complexes containing the well-known cyclometalated N V-dimethyl benzylamine chelate have been treated with NaBArF to extract the chloride ligand. The products, starting from the H-MOP, MeO-MOP, and NC-MOP analogues, are all different. Of particular interest is the product from the H-MOP reaction in that the fourth coordination position is occupied by a weak Pd-C sigma-bond from the naphthyl backbone, on the basis of C-13 NMR data. The rate of product formation in the Pd-catalyzed hydrosilylation of styrene with SiHCl3 has been measured as a function of time for the four auxiliaries H-MOP, MeO-MOP, HO-MOP, and NC-MOP. The NC-MOP is shown to be much faster than the others, and a tentative explanation is offered.

  3,5-Dialkyl Effect on Enantioselectivity in Pd Chemistry:  Applications Involving Both Bidentate and Monodentate Auxiliaries

  摘要：

  The structural 3,5-dialkylphenyl effect on enantioselectivity is demonstrated for several Pd-catalyzed reactions including a ring-opening transmetalation, Heck arylation, and allylic alkylation. For these homogeneously catalyzed reactions the observed enantiomeric excesses (ee's) are found to improve by more than 15%. The ligands tested include MeO-Biphep and a P,N-phosphino-oxazoline-bidentate ligand containing 3,5-di-tert-butylphenyl substituents. Further, several derivatives of the monodentate auxiliary MOP ((R)-2-diarylphosphino-1,1'-binaphthyl) have been modified to include 3,5-dialkylphenyl substituents and these auxiliaries have been tested in Pd-catalyzed enantioselective hydrosilylation chemistry. For some, but not all of these MOP ligands, enhanced ee's of the order of 40-50% are found. Variable-temperature and 2-D NMR studies have been carried out on new model complexes and reveal selected restricted rotation around a number of the P-C(Ipso) aryl bonds. Solid-state structures for two of the new complexes, PdBr(p-NCC6H4)(phosphino-oxazoline, 2b), 8b, and PdCl(C6H4CH2NMe2)(MOP, 4b), 9b, have been determined.
