Integrating electrochemical CO2/CO electrolysers with a downstream bioreactor is one solution for obtaining high-value long-chain products, but the electrolytes in these two systems are mismatched, preventing smooth integration. Here we demonstrate a porous solid electrolyte reactor that produces highly selective and electrolyte-free acetate and couple it with a biosynthesis system for generating C4+ polyhydroxybutyrate bioplastic. A finely tuned electrolyte containing biocompatible salt medium with acetate can be directly injected into the downstream bioreactor without any separation or salt-mixing processes. In the optimized coupled platform, Ralstonia eutropha bacteria can grow with acetate generated from the CO electrocatalytic reduction reactor, and produce bioplastic as the final value-added product. Integrating electrochemical CO electrolysers with a bioreactor can yield high-value long-chain carbon products, but the electrolytes for the two systems are mismatched. Now, a porous solid electrolyte reactor, which can produce acetate directly in bioelectrolyte, is demonstrated. Direct integration with a bioreactor produces bioplastic from CO via the acetate intermediate.","PeriodicalId":74251,"journal":{"name":"Nature synthesis","volume":"3 11","pages":"1392-1403"},"PeriodicalIF":0.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142195629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typical methods require the use of a base, which limits the substrate scope. To mitigate this shortcoming, substantial effort has been made to develop base-tolerant organoboron reagents, efficient catalysts and reaction conditions that do not require external bases. Still, many boronic acids cannot be used or must be independently protected, and many Lewis-basic functional groups poison the catalyst. Here we report a conceptually different SMC reaction that can proceed even under acidic conditions, with a broad substrate scope. Key to this advance is the formation of an acid-stable, palladium-based ion pair between the reaction partners that does not require base for subsequent productive transmetallation. Boronic acids that cannot be used directly in other SMC reactions, such as 2-pyridylboronic acid and boronic acids with strong Lewis bases, can now be used successfully. Suzuki–Miyaura cross-coupling between (hetero)aryl (pseudo)halides and base-sensitive and Lewis-basic (hetero)arylboronic acids is challenging, owing to potential side reactions and catalyst poisoning. Now, the Suzuki–Miyaura cross-coupling of arylthianthrenium salts with (hetero)arylboronic acids, under acidic conditions, is reported, enabling the efficient coupling of base-sensitive and Lewis-basic (hetero)arylboronic acids.","PeriodicalId":74251,"journal":{"name":"Nature synthesis","volume":"3 12","pages":"1490-1497"},"PeriodicalIF":0.0,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44160-024-00631-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142195633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we present a hierarchical assembly strategy to build highly crystalline tubular frameworks. A multi-level assembly process driven by dynamic covalent bonds and coordination bonds is shown to produce a supramolecular nanotubular framework and three tubular covalent organic frameworks (COFs). These materials consist of well-ordered triangular nanotubes assembled in an oriented manner. In tubular COFs, the spacing between adjacent nanotubes can be systematically adjusted by altering the connector lengths to create mesoporous structures with adjustable pore size. Moreover, reversible transformations between tubular COFs and layered COFs were achieved by the reversible addition and removal of Zn(NO3)2. The facile demetallation–remetallation process confers tuneable structural properties to the materials and enables the layered COFs to serve as efficient ‘sponges’ for metal ions. This study represents a notable advance in hierarchical assembly; incorporating covalent bonding into this process is expected to greatly accelerate the development of new materials. Driven by dynamic covalent and coordinate bonding, hierarchical components are formed in situ and assembled in an ordered manner, yielding highly crystalline supramolecular nanotubular frameworks and tubular covalent organic frameworks.","PeriodicalId":74251,"journal":{"name":"Nature synthesis","volume":"3 12","pages":"1498-1506"},"PeriodicalIF":0.0,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142195632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
