Pd-catalysed oscillatory carbonylation reactions: solvent, substrate, catalyst

Data demonstrate that pH oscillations in carbonylation reactions have the potential to occur in a broad range of aliphatic alcohol solutions when using either a small molecule substrate (phenylacetylene) or a polymeric substrate (pegylated alkyne) with either a small molecule catalyst (Pd-diacetate) or a non-leaching polymeric catalyst (Pd-polyacrylate). The alcohols studied are methanol, ethanol, 1-propanol, 1-butanol and 1-hexanol.
