标题 :One-step production of 1,3-propanediol from ethylene oxide and syngas with a cobalt-iron catalyst

摘要:Disclosed is a new catalyst composition comprising a bimetallic Co—Fe catalyst, optionally complexed with a ligand selected from a N-heterocycle, phosphine, or porphorine ligand, that provides a lower cost alternative for the one step synthesis of 1,3-propanediol (1,3-PDO) from ethylene oxide and synthesis gas. For example, a catalyst containing cobalt carbonyl: iron carbonyl with no ligand, or a catalyst containing a cobalt carbonyl: octaethylporphine iron acetate provide moderate yields of 1,3-PDO in a one step synthesis under mild conditions.

摘要:Disclosed is a new catalyst composition comprising a bimetallic Co—Ru catalyst complexed with a N-heterocylcic ligand that is effective, economical, and provides improvements in oxidative stability in the one step synthesis of 1,3-propanediol (1,3-PDO) from ethylene oxide and synthesis gas. For example, cobalt-ruthenium-2,2′-bipyrimidine, 2,2′-dipyridyl, or 2,4,6-tripridyl-s-triazine catalyst precursors in cyclic ether solvents, such as 1,3-dioxolane, 1,4-dioxolane, 1,4-dioxane, and 2-ethyl-2-methyl-1,3-dioxolane, provide good yields of 1,3-PDO in a one step synthesis.

权利人:NITROMED INC
摘要:The invention describes novel cyclooxygenase 2 (COX-2) selective inhibitors and novel compositions comprising at least one cyclooxygenase 2 (COX-2) selective inhibitor, and, optionally, at least one compound that donates, transfers or releases nitric oxide, stimulates endogenous synthesis of nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor or is a substrate for nitric oxide synthase, and/or at least one therapeutic agent. The invention also provides novel kits comprising at least one COX-2 selective inhibitor, optionally nitrosated and/or nitrosylated, and, optionally, at least one nitric oxide donor, and/or, optionally, at least one therapeutic agent. The novel cyclooxygenase 2 selective inhibitors of the invention can be optionally nitrosated and/or nitrosylated. The invention also provides methods for treating inflammation, pain and fever; for treating and/or improving the gastrointestinal properties of COX-2 selective inhibitors; for facilitating wound healing; for treating and/or preventing renal and/or respiratory toxicity; for treating and/or preventing other disorders resulting from elevated levels of cyclooxygenase-2; and for improving the cardiovascular profile of COX-2 selective inhibitors.
