Herein, we report a facile and efficient strategy for one\u2010pot conversion of 1,4\u2010butanediol\u2010based polyesters (BDPs) via equivalent water hydrolysis. The reaction is achieved over 1\u2010butyl\u20103\u2010methyl\u2010imidazolium chloride\u2010ZnCl\n                    <jats:sub>2<\/jats:sub>\n                    \u2010based ionic liquids ([BMIm][Zn\n                    <jats:sub>\n                      <jats:italic>n<\/jats:italic>\n                    <\/jats:sub>\n                    Cl\n                    <jats:sub>\n                      2\n                      <jats:italic>n<\/jats:italic>\n                      \u2009+\u20091\n                    <\/jats:sub>\n                    ]) under mild conditions (e.g., 120 \u00b0C), producing tetrahydrofuran (THF) and corresponding dicarboxylic acids.

Moreover, the catalyst possesses excellent recyclability and can be reused for five consecutive runs without obvious activity attenuation. Mechanism investigation endorses that BDPs are first hydrolyzed to generate acyloxyl alcohol intermediates, which are further converted into THF and dicarboxylic acids through ring\u2010closing C\u2500OH\/C\u2500O metathesis under the cooperation of cation\u2010anion pairs in the ionic liquid catalyst. This work establishes a simple, green, and novel protocol for the selective degradation and valorization of BDPs, holding great potential for practical industrial applications.\n
