The development of a system for the operationally simple, scalable conversion of polyhydroxylated biomass into industrially relevant feedstock chemicals is described. This system includes a bimetallic Pd/Re catalyst in combination with hydrogen gas as a terminal reductant and enables the high-yielding reduction of sugar acids. This procedure has been applied to the synthesis of adipate esters, precursors for the production of Nylon-6,6, in excellent yield from biomass-derived sources.

The desymmetrizing hydroformylation of internal alkenes derived from dihydromuconic acid is described. The study of this reaction afforded easy access to polyfunction aldehydes. After the evaluation of the reactivity of the dimethyl ester derivative with various primary amines, this methodology was used to design a rapid synthesis of (±)-vindeburnol from tryptamine in only two steps.

Dimerization of methyl acrylate by ruthenium-based homogenous catalysts. The effect of the addition of supporting ligands on selectivity was studied. Conversion and selectivity were significantly affected by using triphenyl arsine. Possible reaction mechanism to achieve the tail to tail product was discussed. Catalytic dimerization of methyl acrylate by homogenous ruthenium catalysts was investigated. The effect of the addition of acidic additives, supporting ligands, polymerization inhibitor, and reaction conditions on the selectivity of dimerization was studied, and possible reaction mechanism was discussed. Conversion and selectivity were significantly affected by using triphenylarsine as supporting ligand. Under mild conditions, conversion up to 98% with good selectivity to tail-to-tail product was achieved.
METHOD FOR THE HYDRATION OF A MONOOLEFINICALLY UNSATURATED COMPOUND CARRYING AT LEAST TWO FUNCTIONAL GROUPS

Page/Page column 9; 10, (2008/06/13)
Disclosed is a method for hydrating a monoolefinically unsaturated compound carrying at least two functional groups that are independently selected among a nitrile group, carboxylic acid group, carboxylic acid ester group, and carboxylic acid amide group, to a saturated compound carrying the same at least two functional groups in the presence of a rhodium-containing compound which acts as a catalyst and is homogeneous regarding the reaction mixture.

Protonation of 1-alkylimidazoles provides halogen-free salts which act as ionic liquids and proton reservoir in proton- and metal-assisted catalytic processes like dimerisation of methyl acrylate and ring closing metathesis, and lead to significant improvements both in activity and selectivity.
