摘要:A method for a synthesis of a metal catalyst, including providing at least one metal complex including a metal ion and a non-chelating complexing agent having carbon, the complex having a decomposition temperature, and performing a pyrolysis of the complex at a temperature greater than or equal to a decomposition temperature of the complex, whereby inducing a formation of nanoparticles surrounded by a carbon matrix to form the catalyst. Thanks to the carbon matrix, the catalysts provided herein can be corrosion resistant, self-healing, more cost-effective, and can have higher catalytic activity. The synthesis of the catalyst and its properties can furthermore be improved compared to catalysts formed from a complex including a chelating.

权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:One aspect of the present invention relates to optionally substituted halogenated benzyl halides and the like. These compounds are useful as halogenated benzyl ether-based protecting groups for a variety of functional groups. Another aspect of the present invention relates to use of said protecting groups in an orthogonal protecting group strategy for the synthesis of complex molecules that comprise a number of suitable functional groups. Another aspect of the present invention relates to saccharides bearing various arrays of protecting groups of the present invention. Another aspect of the present invention relates to a method of synthesizing an oligosaccharide or glycoconjugate, comprising the steps of: using a saccharide bearing at least one protecting group of the present invention to glycosylate a second molecule to give a product comprising said saccharide; and removing a protecting group of the present invention from said product.

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.

标题:Synthesis of oligoarylamines, and uses and reagents related thereto
发明人：SINGER ROBERT A; SADIGHI JOSEPH P; BUCHWALD STEPHEN L; MACKEWITZ THOMAS
权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:The transition metal-catalyzed amination of aryl halides, in conjunction with an orthogonal protective group scheme, forms the basis of two routes to oligoaniline precursors. The oligoaniline precursors are soluble in a variety of common organic solvents, and are easily converted to the deprotected oligoanilines. The method allows the preparation of oligoanilines of even or odd chain lengths, and the incorporation of a variety of functional groups into the oligomers. Polyanilines of low polydispersity can also be prepared by this method.
