Towards the molecular Borromean link with three unequal rings: double-threaded ruthenium(ii) ring-in-ring complexes


Veliks, Janis; Seifert, Helen M; Frantz, Derik K; Klosterman, Jeremy K; Tseng, Jui-Chang; Linden, Anthony; Siegel, Jay S (2016). Towards the molecular Borromean link with three unequal rings: double-threaded ruthenium(ii) ring-in-ring complexes. Organic Chemistry Frontiers, 3(6):667-672.

Abstract

This study describes synthetic efforts towards the molecular Borromean link consisting of three unequal rings. The design and strategy involve step by step construction of a ruthenium(II) templated ring-in-ring complex doubly threaded with endocyclic ligands ready for the macrocyclization. The control over the topology is achieved by using specially designed directional building blocks based on 2,2’:6’,2’’-terpyridine. Preliminary macrocyclization attempts utilizing the copper-mediated Eglington reaction provide the mass spectrometric evidence consistent with the ruthenium(II) complex of the molecular Borromean link.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
