A complex of zirconocene with two rq2-alkynyl ligands is described. This complex is the first isolated example of the postulated intermediate in the zirconocene-mediated reductive coupling of alkynes. The development of a Bergman cyclization controlled by metal-ligand interactions is described. Upon complexation with palladium or platinum, phosphine-substituted enediynes rearrange to the aromat...

Cyclic hexamers consisting of a 4-octyl, 4-octyloxy and 4-(2-ethylhexyloxy)triphenylamine unit were synthesized via Buchwald-Hartwig cross coupling reaction using A-A, B-B type monomers in order to avoid the formation other cyclic oligomers such as pentamer heptamer. Unlike different size oligomers, all we examined showed clear cold crystallization 165-240°C DSC thermograms. Resulting character...

Pseudo-benzylic substitution is an important reaction in the ferrocene series, especially to obtain ligands for catalysis. Herein, we described new reactions conditions, using fluorinated alcohols as both solvent and promoter, able deliver iodoferrocene derivatives faster than classical solvents. Various N, O, P C-nucleophiles were found compatible with this transformation which occurs full ret...

This paper presents a new implementation for realising PALplus signals from High-Definition Television (HDTV) transmissions. A proposed encoder design is introduced, which decomposes the HDTV input into two separate channels, the first of which subsamples the input signal to produce the standard resolution TV signal, and the second derives a digitally compressed residual component. The problems...
