Abstract

As part of a programme aimed at exploiting lignin as a chemical feedstock for less oxygenated fine chemicals, several catalytic C-C bond forming reactions utilising guaiacol imidazole sulfonate are demonstrated. These include the cross-coupling of a Grignard, a non-toxic cyanide source, a benzoxazole, and nitromethane. A modified Meyers reaction is used to accomplish a second constructive deoxygenation on a benzoxazole functionalised anisole. [ABSTRACT FROM AUTHOR]

7. Rhodium/phospholane-phosphite catalysts give unusually high regioselectivity in the enantioselective hydroformylation of vinyl arenes.

Author

Abstract

Using the phospholane-phosphite ligand, BOBPHOS, almost perfect regioselectivities and high enantioselectivities (up to 92% ee) are observed in Rh catalysed enantioselective hydroformylation of vinyl arenes. This can be achieved under solvent-free conditions. [ABSTRACT FROM AUTHOR]

8. P–N bond formation as a route to highly electron rich phosphine ligands

Author

Clarke, Matthew L., Cole-Hamilton, David J., Slawin, Alexandra M. Z., and Woollins, J. Derek

Abstract

Phosphines containing two N-bound pyrrolidine groups and one alkyl or aryl group are unusually electron rich σ-donor ligands when compared to either tris(N-pyrrolidinyl)phosphine or trialkyl- and triaryl-phosphines.
