# Tuning zeolite confinement enables catalytic olefin carbonylation

Researchers report a zeolite-catalysed olefin carbonylation process controlled by tuning spatial confinement within the catalyst pores. The work shows how pore geometry can influence catalytic performance in carbonylation reactions. It matters because better control of such reactions could improve routes to industrially useful carbonyl compounds.
