The influence of different spacer lengths on the selectivity of self-assembly processes of bis(bipyridine)-BINOL helicates

The synthesis and self-assembly behaviour of a series of en-antiomerically pure bis(chelating) ligands is reported. The li-gands differ in the spacer unit between a BINOL core and. two bipyridyl groups as the chelating entities and were found to undergo completely diastereoselective self-assembly to di-nuclear double-stranded helicates with silver(I) salts, as dem-onstrated by NMR and CD spectroscopy and ESI mass spec-trometry. Upon coordination to iron(II) or zinc(II) ions, however, a dramatic loss in the diastereoselectivity of the self-assembly of dinuclear triple-stranded helicates was observed, as a result: of increasing spacer length. In the case of zinc(II), the self-assembly processes were even found, to be nonselec-tive with regard to the composition of the helicates.

Synthesis of substituted 2,2′-bipyridines from 2-bromo- or 2-chloropyridines using tetrakis(triphenylphosphine)palladium(0) as a catalyst in a modified Negishi cross-coupling reaction

A protocol for an efficient, modified Negishi cross-coupling strategy for substituted 2,2′-bipyridines employing tetrakis(triphenylphosphine) palladium(0) as a simple, commercially available, and relatively inexpensive catalyst for both 2-bromo- and 2-chl
