Optically pure P-chiral (dialkyl)arylphosphine-boranes having high structural diversity were prepared by two- or three-component coupling of fluorobenzenechromium complexes, P-chiral secondary phosphine-boranes, and other nucleophiles. The stereochernical integrity at the P-stereogenic center was completely retained during the SNAr process when the reaction was carried out in THF at low temperature. (c) 2005 Elsevier Ltd.
