چکیده

The Cu(I)-catalyzed Ullmann condensation reaction between aliphatic alcohols and sym-pentachlorocorannulene provides a convenient entry to 1,3,5,7,9-pentaalkoxycorannulenes. The latter are easily converted to novel deca-heterosubstituted derivatives, such as 1,3,5,7,9-penta-X-2,4,6,8,10-penta-Y-corannulenes by electrophilic aromatic substitution.

Straightforward approach to efficient oxidative DNA cleaving agents based on Cu(II) complexes of heterosubstituted cyclens.

The Cu(II) complexes of cyclen and two of its heterosubstituted analogues were shown to be efficient oxidative DNA cleavers. The reactivity strongly depends on the heteroatom inserted into the macrocycle (O > S > N).

Electron-poor N-substituted imide-fused corannulenes.

N-Substituted imide-fused corannulenes can be generated from the corresponding tetramethylfluoranthenes. Syntheses, crystal structure and electronic properties are reported. The solid state structure of the pentafluorophenyl derivative shows nearly perfect π-stacking in a convex-concave fashion and is expected to possess useful electronic properties.

Recent advances in carbocupration of α-heterosubstituted alkynes

Carbocupration of alpha-heterosubstituted alkynes leads to the formation of stereodefined functionalized vinyl copper species as single isomer. Recent advances in the field show that a simple pre-association of the organometallic derivative with an additional polar functional group in the vicinity of the reaction center may completely change the stereochemical outcome of the reaction. Represent...

Synthesis and X-ray structural analysis of platinum and ethynyl-platinum corannulenes: supramolecular tectons.

The synthesis and characterization of two direct platinum (1 and 6a/b) and three ethynyl-platinum corannulene derivatives (2, 8 and 9), bearing 2, 4, or 5 square planar platinum centers, are presented. The structure of the bowl bearing substituents remains comparable to corannulene and the dynamic behavior of the bowl inversion as assessed by VT NMR supports a persistent bowl structure in solut...

An investigation of the phototoxicity of decabromodiphenyl ether and triclosan

Decabromodiphenylether (deca-BDE) and triclosan (2,4,4'-trichloro-2'hydroxydiphenylether) are used in consumer products as flame retardant and bactericide, respectively. Dermal contact is a major human exposure pathway. Deca-BDE and triclosan are known to be photolytically degraded to compounds like lower-BDEs and dioxins. My hypothesis is that photolysis of deca-BDE and triclosan generates fre...
