Selvakumar, Kumaravel published the artcileCatalytic and Structural Studies on Complexes of a Binaphthyl-Phosphino-Oxazoline Auxiliary: The Meta Dialkyl Effect on Enantioselectivity, Quality Control of 126613-06-7, the publication is Organometallics (2000), 19(7), 1299-1307, database is CAplus.
The chiral phosphino-oxazoline ligand (S,R)-2-(4,5-dihydro-4-isopropyloxazol-2-yl)-2′-bis(3,5-dimethylphenyl)phosphino-1,1′-binaphthyl, 6b, its Pd-dichloro complex, 9, the p-cyanoaryl complex [PdBr(p-NCC6H4)(6b)], 10, a model for the Heck reaction, the cationic 1,3-diphenylallyl derivative [Pd(η3-PhCHCHCHPh)(6b)]OTf, 11, a model for the allylic allylation, and the Rh- and Ir-1,5-COD compounds [M(1,5-COD)(6b)]BF4, 12 and 13, resp., were prepared In enantioselective Heck arylation and allylic allylation catalytic experiments, the presence of the 3,5-dimethylphenyl groups generally increases the observed ee. The solid-state structure of PdCl2(6b), 9, was determined 2-Dimensional and variable-temperature NMR experiments suggest that one of the two 3,5-di-Me P-aryl rings interacts selectively with the remaining ligands. Consequently, the entire chiral pocket becomes slightly more rigid and the correlation with substrate improves.
