Embodiments of the present disclosure provide for Rh(I) catalysts, methods of making alkenyl substituted arenes (e.g., allyl arene, vinyl arene, and the like), methods of making alkyl substituted arenes, and the like.

In one aspect, phosphine compounds comprising three adamantyl moieties (PAd.sub.3) and associated synthetic routes are described herein. Each adamantyl moiety may be the same or different. For example, each adamantyl moiety (Ad) attached to the phosphorus atom can be independently selected from the group consisting of adamantane, diamantane, triamantane and derivatives thereof. Transition metal complexes comprising PAd.sub.3 ligands are also provided for catalytic synthesis including catalytic cross-coupling reactions.

The present invention relates to the field of perfumery. More particularly, it concerns valuable new chemical intermediates for producing perfuming ingredients. Moreover, the present invention comprises also a process for producing compound of formula (I).

##STR00001##

Ligands for use with catalyst compositions used in hydroformylation reactions are described herein. The ligands are used with various solvents and achieve an increase in isoselectivity with an increase in temperature.

A process for producing branched alcohols through isomerization, hydroformylation and hydrogenation.

A catalyst for hydrosilylation is disclosed. The catalyst comprises a complex having a certain formula. A redox-switchable catalyst system for preparing the catalyst is also disclosed. The redox-switchable catalyst system comprises a redox-switchable catalyst and a reducing compound. The reducing compound reduces a formal oxidation state of the redox-switchable catalyst to give the catalyst, where the former is generally inactive in catalyzing hydrosilylation and the latter is catalytically active. A composition comprising the catalyst and/or the redox-switchable catalyst system, and a hydrosilylation reaction product, are also disclosed.

The disclosure provides methods for the production of liquefied petroleum gas from sustainable feedstocks, including methods comprising conversion of alcohols produced by gas fermentation for the production of propane and/or butane.

Diphosphites having an open and a closed 2,4-methylated outer unit and use thereof in hydroformylation.

Mixture of bisphosphites having an open and a closed outer unit and the use thereof as a catalyst mixture in hydroformylation.

A process for producing branched alcohols through isomerization, hydroformylation and hydrogenation.
