Abstract: The regioselectivity of the cobalt-mediated cocyclization of an alkene, an alkyne, and carbon inonoxidc has bccn shown to bc dircctcd by the use of a soft atom, either sulfur or nitrogen, tethered to the alkene partner by a carbon chain. Direction from the homoallylic position is more efficient than from the allylic or bishomoallylic position. A rationale is proposed to explain this observation. Studies on the effect of different alkyl groups on the ...
