✦ Synopsis

The efficiently cobalt(I)-catalysed neutral Diels-Alder type reactions of internal alkynes with substituted 1,3-dienes is described. The regiochemistry for the dihydroaromatic products of reactions of isoprene with unsymmetrical reaction partners (2-alkynes and 1-trimethylsilyl-1-hexyne) is investigated. The dihydroaromatic reaction products are easily oxidised electrochemically to the corresponding functionalised durene and isodurene derivatives.

An ecient cobalt(I)-catalysed homo Diels±Alder reaction of acyclic 1,3-dienes and acetylene derivatives is described. The catalyst system consists of a mixture of a readily available CoBr 2 (dppe) complex, zinc iodide as a cocatalyst, and tetrabutylammonium borohydride as reducing agent. This system
