Nagarkar AA Yasir M Crochet A Fromm KM Kilbinger AF 2016 Use of a tandem ring-opening-ring-closing metathesis (RORCM) strategy for the synthesis of functional metathesis catalysts is reported. Ring opening of 7-substituted norbornenes and subsequent ring-closing metathesis forming a thermodynamically stable 6-membered ring lead to a very efficient synthesis of new catalysts from commercially available Grubbs' catalysts. Hydroxy functionalized Grubbs' first- as well as third-generation catalysts have been synthesized. Mechanistic studies have been performed to elucidate the order of attack of the olefinic bonds. This strategy was also used to synthesize the ruthenium methylidene complex. application/pdf https://sonar.ch/global/documents/95866 eng info:eu-repo/semantics/altIdentifier/doi/10.1002/anie.201604112 info:eu-repo/semantics/altIdentifier/pmid/27592840 info:eu-repo/semantics/openAccess Angewandte Chemie (International ed. in English). - 2016 Grubbs catalysts heterotelechelic polymers olefin metathesis polymerization ruthenium Tandem Ring-Opening-Ring-Closing Metathesis for Functional Metathesis Catalysts. http://purl.org/coar/resource_type/c_6501
