Olefin metathesis, which has been widely used as high-yielding protocols for ring-opening metathesis polymerization (ROMP), ring-closing metathesis (RCM), and isomerization reactions, is typically performed in toxic and volatile solvents such as dichloromethane. In this study, the results of our systematic experiments with the Grubbs G1, G2, and Hoveyda-Grubbs HG2 catalysts proved that benzotrifluoride (BTF) can replace dichloromethane (DCM) in these reactions, providing high yields and similar or even higher reaction rates in certain cases. The ROMP of norbornene resulted not only in high yields but also in polynorbornenes with a high molecular weight at low catalyst loadings. Ring-closing metathesis (RCM) experiments proved that, with the exception of the G1 catalyst, RCM occurs with similar high efficiencies in BTF as in DCM. It was found that isomerization of (Z)-but-2-ene-1,4-diyl diacetate with the G2 and HG2 catalysts proceeds at significantly higher initial rates in BTF than in DCM, leading to rapid isomerization with high yields in a short time. Overall, BTF is a suitable solvent for olefin metathesis, such as polymer syntheses by ROMP and the ring-closing and isomerization reactions.<\/jats:p>","DOI":"10.3390\/ijms24010671","type":"journal-article","created":{"date-parts":[[2023,1,2]],"date-time":"2023-01-02T04:07:09Z","timestamp":1672632429000},"page":"671","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Ring-Opening Metathesis Polymerization and Related Olefin Metathesis Reactions in Benzotrifluoride as an Environmentally Advantageous Medium"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3939-6925","authenticated-orcid":false,"given":"Ervin","family":"Kov\u00e1cs","sequence":"first","affiliation":[{"name":"Polymer Chemistry and Physics Research Group, Institute of Materials and Environmental Chemistry, Research Centre for Natural Sciences, Magyar Tud\u00f3sok Krt. 2, H-1117 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bence","family":"Balterer","sequence":"additional","affiliation":[{"name":"NMR Research Laboratory, Centre for Structural Science, Research Centre for Natural Sciences, Magyar Tud\u00f3sok Krt. 2, H-1117 Budapest, Hungary"},{"name":"Hevesy Gy\u00f6rgy PhD School of Chemistry, E\u00f6tv\u00f6s Lor\u00e1nd University, P\u00e1zm\u00e1ny S\u00e9t\u00e1ny 1, H-1117 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nguyen","family":"Anh Duc","sequence":"additional","affiliation":[{"name":"Polymer Chemistry and Physics Research Group, Institute of Materials and Environmental Chemistry, Research Centre for Natural Sciences, Magyar Tud\u00f3sok Krt. 2, H-1117 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gy\u00f6rgyi","family":"Szarka","sequence":"additional","affiliation":[{"name":"Polymer Chemistry and Physics Research Group, Institute of Materials and Environmental Chemistry, Research Centre for Natural Sciences, Magyar Tud\u00f3sok Krt. 2, H-1117 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael C.","family":"Owen","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, University of Miskolc, H-3515 Miskolc-Egyetemv\u00e1ros, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Attila","family":"Domj\u00e1n","sequence":"additional","affiliation":[{"name":"NMR Research Laboratory, Centre for Structural Science, Research Centre for Natural Sciences, Magyar Tud\u00f3sok Krt. 2, H-1117 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2475-6841","authenticated-orcid":false,"given":"B\u00e9la","family":"Iv\u00e1n","sequence":"additional","affiliation":[{"name":"Polymer Chemistry and Physics Research Group, Institute of Materials and Environmental Chemistry, Research Centre for Natural Sciences, Magyar Tud\u00f3sok Krt. 2, H-1117 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1746","DOI":"10.1021\/cr9002424","article-title":"Ruthenium-based heterocyclic carbene-coordinated olefin metathesis catalysts","volume":"110","author":"Vougioukalakis","year":"2010","journal-title":"Chem.
