                            Bi-functional cobalt-containing catalysts useful for making stereospecific compounds and compositions, along with methods of making, and uses thereof in the syntheses of optically pure β-lactones from aldehydes and ketene are described. Precursors, intermediates, compositions, and particular features of the use if the compositions, such as high enantiomeric selectivity, high yield and low mole percent of catalyst useful are provided.
