The invention relates to bisphosphites having 2,4-tert-butylphenyl units and a method for the preparation thereof. Furthermore, the invention relates to the use of the compounds as ligands in a ligand-metal complex. The compound, and also the complex, may be used as a catalytically active composition in hydroformylation reactions.

Disclosed are highly active cationic cobalt phosphine complexes, both mono- and bimetallic, that can catalyze hydroformylation reactions. The disclosed catalysts can be utilized in methods that provide reaction processes that are hundreds of times faster than high pressure HCo(CO).sub.4 or phosphine-modified HCo(CO).sub.3(PR.sub.3) catalysts and operate at considerably lower pressures and temperatures. Also disclosed are methods of hydroformylation using the described transition metal complexes. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Provided are a novel ionic solid usable for a secondary battery and demonstrating a high ionic conductivity, and an ionic conductor containing the same.

A homogeneous catalytic reaction method and a catalyst for isomerization and hydroformylation of long-chain internal olefins are disclosed. A rhodium-ruthenium metal complex is used as a catalyst; and the ligands are tetradentate phosphine ligands. By means of the catalytic system, homogeneous internal olefin isomerization aid hydroformylation can be performed under a certain temperature and pressure to obtain aldehyde products having high normal to iso ratios. The present invention is applicable to not only long-chain internal olefins (C8) but also internal olefins having a carbon number less than 8.

Methods for deposition of elemental metal films on surfaces using metal coordination complexes comprising nitrogen-containing ligands are provided. Also provided are nitrogen-containing ligands useful in the methods of the invention and metal coordination complexes comprising these ligands.

The present invention provides biologically active compounds and methods to obtain biologically active compounds that can be used as photosensitizers for diagnostic and therapeutic applications, particularly for PDT of cancer, infections and other hyperproliferative diseases, fluorescence diagnosis and PDT treatment of non-tumorous indications such as arthritis, inflammatory diseases, viral or bacterial infections, dermatological, ophthalmological or urological disorders. As the compounds exhibit also toxicity against targets (tumor cells, bacteria, inflammation-related cells) without light these biologically active compounds may also be used for the light-independent treatment of such indications. Preferred embodiments of the present invention consist of methods to synthesize metal or half-metal complex structures incorporating one or more substituted 2,3,5,6-tetrafluorophenyl-dipyrromethene (2,3,5,6-tetrafluorophenyldipyrrin) units. These dipyrromethenes (dipyrrins) can carry a variety of different substituents in the 4-position enabling a fine tuning of their biological or amphiphilic/hydrophilic properties. Another object of the present invention is to provide amphiphilic compounds with a higher membrane affinity and increased efficacy.

Methods for deposition of elemental metal films on surfaces using metal coordination complexes comprising nitrogen-containing ligands are provided. Also provided are nitrogen-containing ligands useful in the methods of the invention and metal coordination complexes comprising these ligands.

The production of 2-propylheptanol described here is effected via Rh-catalyzed hydroformylation of C.sub.4-olefin to afford C.sub.5-aldehyde, aldol condensation to afford the C.sub.10-aldehyde and hydrogenation to afford the C.sub.10-alcohol. The emphasis is on the hydroformylation and the ligand employed therein. The problem addressed by the invention is that of reducing the costs of 2PH production. This problem is solved when a cheaper catalyst system which simultaneously achieves a better regioselectivity is employed in the hydroformylation. This catalyst system contains rhodium as the central atom and is complexed with the ligand (1): ##STR00001##
