摘要： A method of forming TiO2—ZnO nanoparticles coated by a copper (II) complex includes forming a mononuclear copper complex by treating a ligand with Cu2+ ions; and immobilizing the mononuclear copper complex on TiO2—ZnO nanoparticles to obtain the TiO2—ZnO nanoparticle coated by the copper (II) complex. The TiO2—ZnO nanoparticles coated by a copper (II) complex thus produced have improved catalytic effectiveness and increased efficiency by reducing catalytic reaction time and temperature, particularly in methods of catalyzing oxidation of an alcohol or of catalyzing decarboxylative bromination of an acid.

The reactant may further include water in the form of steam. The reactant is introduced to a perovskite catalyst in the reactor. The perovskite catalyst promotes the formation of the higher carbon compounds from ethanol, and may be in the form of a powder or thin film. The perovskite catalyst has the formula ABO3, wherein A is one or more selected from a group consisting of La and Sr, and wherein B is one or more selected from a group consisting of Mn, Ca, Fe, and Co. The perovskite catalyst particularly may be La0.7Sr0.3MnO3. The obtained higher carbon compounds may include at least one of acetone and crotonaldehyde.

摘要： Embodiments herein concerns the eco-friendly conversion of simple alcohols to linear or branched functionalized alkanes, by integrated catalysis. The alcohols are firstlyoxidized either chemically or enzymatically to the corresponding aldehydes or ketones, followed by aldol condensations using a catalyst to give the corresponding enals or enones. The enals or enones are subsequently and selectively hydrogenated using a recyclable heterogeneous metal catalyst, organocatalyst or an enzyme to provide linear or branched functionalized alkanes with an aldehyde, keto- or alcohol functionality. The process is also iterative and can be further extended by repeating the above integrated catalysis for producing long-chain functionalized alkanes from simple alcohols.

摘要： The present invention provides processes for preparing a prostacyclin analog of Formula (I) or a pharmaceutically acceptable salt thereof, wherein R10 is a linear or branched C1-6 alkyl. The processes of the present invention comprise steps that generate improved yields and fewer byproducts than traditional methods. The processes of the present invention employ reagents (e.g., the oxidizing reagent) that are less toxic that those used in the traditional methods (e.g., oxalyl chloride). Many of the processes of the present invention generate intermediates with improved e.e. and chemical purity; thereby eliminating the need of additional chromatography steps. And, the processes of the present invention are scalable to generate commercial quantities of the final compound.
