摘要：

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. (C) 2001 Elsevier Science Ltd. All rights reserved.
