Propylene
carbonate is an excellent solvent for rhodium-catalysed intermolecular alkyne hydroacylation reactions, allowing a variety of β-S-aldehydes and alkynes to be combined in high yields, to deliver enone products. The effective use of propylene carbonate removes the need to employ dichloroethane as solvent.

The use of the electron-rich diphosphine ligand, dcpe, allows the efficient and highly linear selective hydroacylative coupling of aldehydes, including aryl examples, with a range of alkynes.
