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"]]

The complete molecule of the (syn,syn) form is generated by a crystallographic twofold axis. The geometries of both conformers are compared in detail, revealing no significant differences in bond lengths, despite different bond angles because of the conformational changes. Analysis of the intermolecular interactions, aided by Hirshfeld surfaces, shows distinctive SS and SN contacts only for the (syn,anti) conformer. Aromatic –-stacking interactions are found for both conformers, which occur for the (syn,anti) conformer between pairs of molecules, but are continuous stacks in the (syn,syn) conformer. Non merohedral twinning was found for the crystal of the (syn,anti) conformer used for data collection."],["dc.identifier.doi","10.1107/S2056989020008105"],["dc.identifier.doi","10.1107/S2056989020008105/hb7924sup1.cif"],["dc.identifier.doi","10.1107/S2056989020008105/hb7924sssup3.hkl"],["dc.identifier.doi","10.1107/S2056989020008105/hb7924sasup4.hkl"],["dc.identifier.doi","10.1107/S2056989020008105/hb7924sssup4.cml"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/17674"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/91717"],["dc.language.iso","en"],["dc.notes.intern","Migrated from goescholar"],["dc.relation.eissn","2056-9890"],["dc.relation.issn","2056-9890"],["dc.relation.orgunit","Fakultät für Chemie"],["dc.rights","CC BY 4.0"],["dc.rights.access","openAccess"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.subject","crystal structure; trithiocarbonates; benzothiazole; polymorphism; Hirshfeld surface analysis"],["dc.subject.ddc","540"],["dc.title","Polymorphism of bis(1,3-benzothiazol-2-yl) trithiocarbonate"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
