A novel and efficient Pd-catalyzed C-H acetoxylation is described. The approach uses R2(O)P as a directing group to synthesize various substituted 2′-phosphorylbiphenyl-2-OAc compounds. Notably, the reaction exhibits smooth operation under mild conditions and shows good functional group tolerance. Products are obtained with high selectivity and yields.

Enantioselective catalysis 113: New menthylphosphane ligands differing in steric and electronic properties

, p. 45 - 55 (2007/10/03)
A concept for bisphosphane ligands was developed, in which chirality is derived from the optically active (1R,3R,4S)-menthyl substituents in PMen2 groups and the backbone between the phosphorus units is varied (o-phenylene, 2,2'-biphenylene, 1,1'-ferrocenediyl); one of the two PMen2 groups was also replaced by a PPh2 unit. The synthesis and characterisation of seven new menthylphosphanes is described. Emphasis is put on the NMR assignment of the menthyl protons by two-dimensional methods and 13C-1H shift correlation. The ligands have been used in Rh and Ni complexes in several model reactions of enantiosclective catalysis giving optical inductions in the low to middle range.
