Diels-Alder reactions of cis-2-chlorovinyltributylstannane are greatly accelerated by the presence of catalytic amounts of haloboranes. Mechanistic studies support a mechanism for the catalysis involving an intermediate boron-aclivated dienophile. A simil
Synthesis of cyclic sulfones by ring-closing metathesis.

A general and highly efficient synthesis of cyclic sulfones based on ring-closing metathesis has been developed. The synthetic utility of the resulting cyclic sulfones was demonstrated by their participation in stereoselective Diels-Alder reactions and transformation to cyclic dienes by the Ramberg-Baecklund reaction.
In situ formation of alkenyl- and alkynylboranes for Diels-Alder reactions by boron-silicon exchange with alkenyl- and alkynylsilanes

A variety of alkenylsilanes underwent transmetallation with BBr3 to afford the corresponding alkenyldibromoboranes in solution. Similarly, the transmetallation of alkynylsilanes with BCl3 afforded alkynyldichloroboranes, A number of the alkenyl- and alkynylboranes are novel and useful Diels-Alder dienophiles. An ionic mechanism for the transmetallation is proposed.
