Zinc-based catalysts have the advantages of being low cost, being non-toxic, having high activity, and having excellent environmental and biological compatibility. Zinc (II) acetylacetonate (Zn(Acac)2) was first reported as a highly effective catalyst for the melt transesterification of biphenyl carbonate with 1,4-butanediol to synthesize poly(1,4-butylene carbonate)(PBC). It was found that the weight-average molecular weight of PBC derived from Zn(Acac)2 could achieve 143,500 g\/mol with a yield of 85.6% under suitable reaction conditions. The Lewis acidity and steric hindrance of Zn2+ could obviously affect the catalytic performance of Zn-based catalysts for this reaction. The main reasons for the Zn(Acac)2 catalyst displaying a higher yield and Mw than other zinc-based catalysts should be ascribed to the presence of the interaction between acetylacetone ligand and Zn2+, which can provide this melt transesterification reaction with the appropriate Lewis acidity as well as the steric hindrance.<\/jats:p>","DOI":"10.3390\/molecules27248958","type":"journal-article","created":{"date-parts":[[2022,12,16]],"date-time":"2022-12-16T03:55:39Z","timestamp":1671162939000},"page":"8958","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Synthesis of Aliphatic Polycarbonates from Diphenyl Carbonate and Diols over Zinc (II) Acetylacetonate"],"prefix":"10.3390","volume":"27","author":[{"given":"Jun","family":"Feng","sequence":"first","affiliation":[{"name":"Key Laboratory for Green Process of Chemical Engineering of Xinjiang Bingtuan, School of Chemistry and Chemical Engineering, Shihezi University, Shihezi 832003, China"},{"name":"Xinjiang Tianye (Group) Coporation Limited, Shihezi 832000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin","family":"Li","sequence":"additional","affiliation":[{"name":"Xinjiang Tianye (Group) Coporation Limited, Shihezi 832000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Feng","sequence":"additional","affiliation":[{"name":"Key Laboratory for Green Process of Chemical Engineering of Xinjiang Bingtuan, School of Chemistry and Chemical Engineering, Shihezi University, Shihezi 832003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhong","family":"Wei","sequence":"additional","affiliation":[{"name":"Key Laboratory for Green Process of Chemical Engineering of Xinjiang Bingtuan, School of Chemistry and Chemical Engineering, Shihezi University, Shihezi 832003, China"},{"name":"Xinjiang Tianye (Group) Coporation Limited, Shihezi 832000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziqing","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory for Green Process of Chemical Engineering of Xinjiang Bingtuan, School of Chemistry and Chemical Engineering, Shihezi University, Shihezi 832003, China"},{"name":"Xinjiang Tianye (Group) Coporation Limited, Shihezi 832000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoling","family":"Song","sequence":"additional","affiliation":[{"name":"Key Laboratory for Green Process of Chemical Engineering of Xinjiang Bingtuan, School of Chemistry and Chemical Engineering, Shihezi University, Shihezi 832003, China"},{"name":"Xinjiang Tianye (Group) Coporation Limited, Shihezi 832000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8594","DOI":"10.1038\/ncomms9594","article-title":"Crystalline CO2-based polycarbonates prepared from racemic catalyst through intramolecularly interlocked assembly","volume":"6","author":"Liu","year":"2015","journal-title":"Nat.
