A compound represented by the structure of formula (I): ##STR00001## The compound is useful as a ligand for ruthenium to form an organometallic complex. The complex may be immobilized on an oxidic support to form an active, heterogeneous catalyst for the hydrogenolysis of amides to form amines and optionally alcohols.

The present invention relates to improved processes for the preparation of ruthenium or osmium complexes comprising P and N donor ligands, in particular, ruthenium complexes.

Provided herein are photochemical separations. The methods herein can include exposing a first metal complex and a second metal complex to light to facilitate an irreversible chemical reaction to form a modified first metal complex. The modified first metal complex then may be separated from the second metal complex. Compositions also are provided.

Compositions and methods of capturing one or more nucleic acid molecules of a cell or subcellular compartment are described. In certain aspects, the compositions comprise a caged molecule comprising one or more photolinkers and an antisense oligonucleotide, which when uncaged hybridizes to a target nucleic acid molecule.

The present application discloses complexes useful as catalysts for organic chemical synthesis including hydrogenation and dehydrogenation of unsaturated compounds or dehydrogenation of substrates. The range of hydrogenation substrate compounds includes esters, lactones, oils and fats, resulting in alcohols, diols, and triols as reaction products. The catalysts of current application can be used to catalyze a hydrogenation reaction under solvent free conditions. The present catalysts also allow the hydrogenation to proceed without added base, and it can be used in place of the conventional reduction methods employing hydrides of the main-group elements. Furthermore, the catalysts of the present application can catalyze a dehydrogenation reaction under homogenous and/or acceptorless conditions. As such, the catalysts provided herein can be useful in substantially reducing cost and improving the environmental profile of manufacturing processes for variety of chemicals.
