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.研究表明，在羰基化反应中，当使用小分子底物（苯乙炔）或聚合物底物（聚乙二醇化炔烃）与小型分子催化剂（Pd-二乙酸）或非溶出聚合物催化剂（Pd-聚丙烯酸酯）进行反应时，脂肪族醇溶液中可能发生pH振荡。所研究的醇包括甲醇、乙醇、1-丙醇、1-丁醇和1-己醇。
