Organometallic chemistry of the transition metals XXIII. Some indenyl and fluorenyl derivatives of manganese carbonyl

An overview of the area of organocatalytic asymmetric acyl transfer processes is presented including O- and N-acylation. The material has been ordered according to the structural class of catalyst employed rather than reaction type with the intention to draw mechanistic parallels between the manner in which the various reactions are accelerated by the catalysts and the concepts employed to control transfer of chiral information from the catalyst to the substrates.

Reaction des p-phenylphospholes avec le dicyclopentadienyl-difer-tetracarbonyle, synthese et etude spectrochimique des phosphaferrocenes

Die Umsetzung von 2.4.6-Triphenyl-phosphorin mit Chromhexacarbonyl liefert in siedendem Dibutylather rotbraunes 2.4.6-Triphenyl-phosphorin-chrom(0)-tricarbonyl. Die IR-, NMR-und Massenspektren der Verbindung sprechen fur ein π-gebundenes Phosphorinsystem.

Reaction of 2,4,6-triphenylphosphorine with chromium hexacarbonyl in boiling dibutyl ether affords the red-brown crystalline (2,4,6-triphenylphosphorine) chromium (0) tricarbonyl. The i. r., n.m.r., and mass spectra of this complex suggest a π-bonded phosphorin ring system.

Triphenylphosphorin-chrom(0)-tricarbonyl

The synthesis and characterization of a series of heteroleptic ruthenium(II) dyads derived from pyrrole-2-carboxylate thionoesters are reported. Ligands bearing a conjugated thiocarbonyl group were found to be more reactive toward Ru(II) complexation compared to analogous all-oxygen pyrrole-2-carboxylate esters, and salient features of the resulting complexes were determined using X-ray crystallography, electronic absorption, and NMR spectroscopy. Selected complexes were evaluated for their potential in photobiological applications, whereupon all compounds demonstrated in vitro photodynamic therapy effects in HL-60 and SK-MEL-28 cells, with low nanomolar activities observed, and exhibited some of the largest photocytotoxicity indices to date (>2000). Importantly, the Ru(II) dyads could be activated by relatively soft doses of visible (100 J cm–2, 29 mW cm–2) or red light (100 J cm–2, 34 mW cm–2), which is compatible with therapeutic applications. Some compounds even demonstrated up to five-fold selectivit...
