TL;DR: These studies suggest that the weak interactions between the Cu(II) ions and the perchlorate anions detected in the crystal structures are important to introduce significant distortions in the heterobridged cores of 1 and 2, which clearly affect the nature and strength of the superexchange interactions.

TL;DR: In this paper, the synthesis and characterization of the copper(II) complex [Cu2(dpt)2{(μ-O2C)[(η5-C5H4)Fe( η5 − C5H5)]}2](ClO4)2 (1), where dpt = dipropylenetriamine, are reported, and its structure was determined by single-crystal X-ray analysis.

TL;DR: In this paper, two different stragies for the synthesis of pentacyclic Strychnos alkaloids in enantiomerically pure form are explored, which involve the use of enantiopure 2-(4-piperidylmethyl)indoles prepared by kinetic resolution of 1-(3-pyridyl)ethanol, followed by partial reduction of the pyridine ring to the tetrahydropyridine level, Claisen rearrangement of the resulting allylic alcohol, and finally Smith indolization.

TL;DR: The first tetrametallic compound containing a [Cu2{μ-O2C[ (η5-C5H4)Fe(η 5-C 5H5)]}2+ core is synthesized and X-ray analysis shows π-stacking interactions between the terminal bidentate 2,2‘-bipyridine ligands.

TL;DR: The natural tendency of 1,4-dihydropyridines to undergo "biomimetic" oxidation to afford pyridinium salts can be switched off and, through the use of reagents that interact electrophilically with the enamine moiety present in the heterocyclic system, it is possible to promote alternative oxidations.
