Abstract

The complexes formed on mixing Ti(OiPr)4 and bicyclo-octanediols (BODOLs) 1 and 2 (1:1) are useful as chiral catalysts in asymmetric reductions and were investigated by 1HNMR-spectroscopy and by computational methods. A consistent picture emerged of head-to-tail dimers being kept together via a Ti-O-Ti-O m-oxo bridge similar to the Ti-tartrates but different from the corresponding Ti-BINOLates and the Ti-TADDOLates.
