Abstract
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 acohols 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.
