14. Dicyclohexyboron chloride was used as received (Aldrich Chemical Co.). Other dialkylboron chlorides were prepared according to literature procedures. See: Brown, H. C.; Dhar, R. K.; Ganesan, K.; Singaram, B. J. Org. Chem. 1992, 57, 499.
15. The reaction times vary. Primary alkyl groups react more slowly than secondary alkyl groups. We have observed reaction times as long as 10 h for the formation of the intermediate as well as the alkyl rearrangement reaction.
