phosphine-catalyzed 1,2-diacylation of alkynes using acylfluorides and acylsilanes as acyl sources. The key to the success of the reaction is a formal oxidative addition–ligand metathesis–reductive elimination cycle based on phosphine redox catalysis, which allows for the installation of two different acyl groups into an alkyne in a regioselective manner.
