Abstract
Dimethyl acetylenedicarboxylate (DMAD) has been used as the alkyne component in the Khand reaction with norbornene under both thermal and N-oxide promoted conditions. Its thermolysis under CO pressure has also been reinvestigated and the structure of one of the trinuclear rearrangement products, MeO2C·CH2CCo3(CO)9, confirmed by X-ray crystallography; (MeOOC)2CHCH(COOMe)2 is the principal metal-free product from this reaction. Methyl but-2-ynoate undergoes similar rearrangement yielding MeO2C·CHMe·CCo3(CO)9.
