Both erythro and threo isomers of B-(3,3-dimethyl-1,2-dideuterio-1-butyl)-9-BBN (6) were prepared from 3,3-dimethyl-1-butyne (4) through a hydroboration-deuteronolysis-hydroboration sequence employing first 9-BBN-H and then 9-BBN-D, or in reverse order, respectively. Employing the Whitesides protocol, the stereochemistry of B --> Pd alkyl group
