AI Technical Summary

Technical Problem

Existing technologies make it difficult to directly convert olefins into esters without separating intermediates to form an alcohol moiety, and the alcohol moiety lacks a carbon atom.

Method used

By using a combination of Ru catalyst, imidazole ligand and acidic compound, olefins are directly converted into esters through a chain of hydroformylation/hydrogenation/esterification reactions, with an additional carbon atom added to the alcohol moiety.

Benefits of technology

This process enables the direct conversion of olefins into esters, avoiding intermediate separation steps and improving efficiency and selectivity.
