Bis (alpha-hydroxyalkyl)phenylphosphines react with alpha-iminoboranes in protic solvents such as dihydric alcohols to give 2-(1',1'-dibutylamyl)-4,6-di-R-5-phenyl-1,3,2,5-dioxaboraphosphorinanes, which react with CuI in pyridine to form [LCuI(Py)] complexes. PMR spectroscopy showed that the phosphorus-containing ligands exist as a single stereoisomer.
