Coupling of Internal Alkynes in TpMe2Ir Derivatives:  Selective Oxidation of a Noncoordinated Double Bond of the Resulting Iridacycloheptatrienes

The reaction of different TpMe2Ir derivatives and dimethylacetylene dicarboxylate (DMAD) allows the preparation of three different metallacycloheptatriene complexes and an unusual allyl-terminated metallacycle. The C atoms of distant CC bonds in the metallacycles, including aromatic ones, can be co...

Description
Summary:The reaction of different TpMe2Ir derivatives and dimethylacetylene dicarboxylate (DMAD) allows the preparation of three different metallacycloheptatriene complexes and an unusual allyl-terminated metallacycle. The C atoms of distant CC bonds in the metallacycles, including aromatic ones, can be converted selectively to the corresponding keto functionality under mild conditions.
