However, many reported protocols suffer from common limitations, such as the usually harsh reaction conditions, with the related safety issues, and the requirement of high catalyst loadings. Recent research efforts have demonstrated that the application of flow technologies to C–H functionalization reactions can significantly mitigate these issues, also resulting in more sustainable protocols. In this chapter we present selected examples of C–H functionalizations realized in flow conditions, highlighting the sustainability aspects effected by the application of flow techniques.","PeriodicalId":202204,"journal":{"name":"Green Chemistry Series","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126424365","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}

Significant research has, therefore, been invested towards the design and synthesis of new polymers using a variety of polymerisation techniques to deliver specifically tailored structures with refined macromolecular structures including tailoring parameters such as molecular weight, polydispersity and tacticity. One interesting approach, which has started to demonstrate value in the synthesis of polymers, is the conducting of polymerisation processes in a dynamic continuous flow scenario. Flow polymerisation has been shown to facilitate access to new polymers which cannot be synthesised or would be difficult to prepare under conventional batch conditions through improved control over the various reaction parameters. In this chapter, a brief selective overview is given of the various syntheses of polymers and polymeric particles that have been reported in the literature via flow processes to date.","PeriodicalId":202204,"journal":{"name":"Green Chemistry Series","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124764350","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}

Making the change from a traditional batch manufacturing paradigm to a new continuous paradigm can be highly disruptive. In this chapter, key enablers for running continuous processes including multi-step processes are presented. These enablers allow the process to run in a state of control such that the environmental, safety, quality and cost benefits associated with continuous processing may be realized. The enablers include the use of process analytical technology, a material tracking system, a diversion strategy and the incorporation of surge capacity. Examples from the field where these control strategy enablers were successfully used to produce drug substance API using continuous technology under cGMP conditions are also presented. In these case studies the environmental, safety and quality benefits realized are highlighted and the evolution of the technology from single step batch-continuous hybrid processes to multi-step fully continuous telescoped processes is described.","PeriodicalId":202204,"journal":{"name":"Green Chemistry Series","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128966804","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}

Increasingly though flow processing regimes are being successfully implemented to allow better control over reaction parameters and facilitate a more consistent processing environment; this has also shown promising results for challenging reactions such as ionic polymerisation. Furthermore, as flow chemistry is becoming more widely implemented additional and complementary processing tools such as photochemical, supported reagents and enzymatic based plug-in reactors are being evaluated for their ability to expand the range of polymers on offer. Supplementing this era of advanced and accelerated synthesis is an explosion in direct integrated analysis routines and the development of smart self-optimising platforms capable of self-sustained assembly of new polymers. Whilst the machines have been taking over the physical synthesis, chemists have been starting to think beyond simply the isolated stage of polymer synthesis, considering options to create more encompassing work-flows. The next generations of polymer synthesis will encompass all aspects of synthesis, purification and final analysis as a single unified sequence. These new polymer products will ultimately be used for new applications such as light-emitting diodes and in photovoltaics.","PeriodicalId":202204,"journal":{"name":"Green Chemistry Series","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131223456","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}
