The reaction of o-iodobenzoic acid with various acetylenic compounds in the presence of a palladium catalyst leads to phthalides [1-(3H)isobenzofuran-3-ones] as major products and isocoumarins as minor products.

The palladium–copper-catalysed heteroannulation of o-iodobenzoic acid 3 with terminal alkynes 4–18 leads to the synthesis of (Z)-3-alkylidenephthalides 19–33 as the major products. In certain cases, the formation of isocoumarins 34–37 is also observed.
