The scalable preparation, easy handling and broad substrate scope of the electrophilic cyanation promoted by 9, which includes amines, thiols, silyl enol ethers, alkenes, electron rich (hetero)arenes and polyaromatic hydrocarbons, illustrate the synthetic potential of this reagent. Importantly, Lewis acid activation of the reagent is not required for the transfer process. We additionally report herein biomimetic cyanocyclization cascade reactions, which are not promoted by typical electrophilic cyanation reagents, demonstrating the superior ability of 9 to trigger challenging transformations."],["dc.identifier.doi","10.1002/anie.201904557"],["dc.identifier.eissn","1521-3773"],["dc.identifier.issn","1433-7851"],["dc.identifier.pmid","31091342"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/16427"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/91716"],["dc.language.iso","en"],["dc.notes.intern","Migrated from goescholar"],["dc.relation.issn","1521-3773"],["dc.relation.orgunit","Fakultät für Chemie"],["dc.rights","CC BY-NC-ND 4.0"],["dc.rights.access","openAccess"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc-nd/4.0"],["dc.subject","electrophilic cyanation; metal-free functionalizations; sulfonium salts; transfer reagents; umpolung"],["dc.subject.ddc","540"],["dc.title","5-(Cyano)dibenzothiophenium Triflate: A Sulfur-Based Reagent for Electrophilic Cyanation and Cyanocyclizations"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
