HETEROANNULATION OF ALKYNYL CARBENE COMPLEXES - [3+2] DIPOLAR CYCLOADDITION OF PENTACARBONYL-[(ALKYNYL)(METHOXY)CARBENE]METALS WITH MASKED 1,3-DIPOLES

摘要

Pentacarbonyl[(alkynyl)(methoxy)carbene]metals undergo[3+2] dipolar cycloaddition on treatment with masked azomethine imine or azimine ylides to give pentacarbonyl[(alkyl or arylheteryl)(methoxy)carbene]metals in good yields (40-85%). [References: 11]
