  On the behaviour of dimethyl acetylenedicarboxylate in carbonylation and Khand reactions

  摘要：

  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)(2)CHCH(COOMe)(2) is the principal metal-free product from this reaction. Methyl but-2-ynoate undergoes similar rearrangement yielding MeO2C . CHMe . CCo3(CO)(9). (C) 1999 Elsevier Science S.A. All rights reserved.
