| Popis: | 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, MeO 2 C · CH 2 CCo 3 (CO) 9 , confirmed by X-ray crystallography; (MeOOC) 2 CHCH(COOMe) 2 is the principal metal-free product from this reaction. Methyl but-2-ynoate undergoes similar rearrangement yielding MeO 2 C · CHMe · CCo 3 (CO) 9 . |
