Transfer hydroformylation for the production of oxygenates
The present disclosure provides a method for forming oxygenates from olefins which includes hydroformylation of aldehydes as a formyl source alternative to syngas. In at least one embodiment, a hydroformylation process is performed at low-temperature and at or near ambient pressure for the conversion of olefins into aldehydes, thus reducing the formation of by-products such as via double bond or skeletal isomerization of the feedstock; or via further conversion of the formed aldehydes and alcohols. In at least one embodiment, the use of gaseous olefinic products (e.g., ethylene) instead of strained olefins (e.g., norbornene) improves the control equilibria in transfer hydroformylation reactions.

Method for preparation of fluoro, chloro and fluorochloro alkylated compounds by homogeneous catalysis
The invention discloses a method for preparations of fluoro, chloro and fluorochloro alkylated compounds by homogeneous Pd catalyzed fluoro, chloro and fluorochloro alkylation with fluoro, chloro and fluorochloroalkyl halides in the presence of di(1-adamantyl)-adamantyl-n-butylphosphine and in the presence of 2,2,6,6-tetramethylpiperdine 1-oxyl.
Organic compounds
A process of converting a carbon-carbon multiple bond to a cyclopropane ring, comprising the addition of a N-alkyl-N-nitroso compound to a mixture of alkene precursor, aqueous base and Pd(II)-catalyst, with the N-alkyl-N-nitroso compound obtained directly from an alkyl amine derivative, NaNO.sub.2 and an acid via phase separation of the N-alkyl-N-nitroso compound from the aqueous phase.
