SYNTHESIS OF 7,7-DIMETHYLBICYCLO-OCTANE BY ACETYLATING A DICOBALTOHEXACARBONYL 4-METHYLPENT-3-EN-1-YNE-1 COMPLEX

Article abstract of DOI:10.1007/BF00956963

Dicobaltohexacarbonyl 4-methyl-pent-3-en-1-yne complexes have been acylated with acryloyl and crotonoyl tetrafluoroborates followed by methanolysis to make acylmethoxy adducts containing hem-dimethyl moieties.Conditions have been defined under which such adducts containing enone systems are selectively reduced to allyl alcohols with retention of the cobaltocarbonyl moieties.The latter can be converted by Quand-Poson reaction to the inaccessible polyfunctional derivatives of 7,7-dimethylbicyclo<3.3.0>octane.
