Ni(COD)z/Ph3P or Ni(acac)2/Et3Al/PhsP have been shown to be effective catalysts for the stereoselective homo Diels-Alder reaction between norbomadiene and electron deficient olefins. High and opposite stereoselectivity was observed for cyclic and acyclic enones. Vinyl sulfoxides gave predominantly o

The activation and reaction volumes (βV /βV) were showing negative volumes of activation (βV Ο½ 0) whereas the others are slightly retarded (βV ΟΎ 0). From the analysis determined for the retro Diels-Alder reactions of the parent dihydrobarrelene 1a, its 2-cyano derivative 1b, the exo and of the volum
