摘要:The invention relates to a method for preparing carbene by means of deprotonation of a precursor salt using a strong base. A purpose of the invention is to enhance the synthesis of carbenes, i.e. to simplify same, to make said synthesis more economical and to obtain a liquid or solid, stable and pure form constituting a catalytic system that is easy to store and use and that has a higher efficiency, higher yield and higher selectivity than carbene catalysts of the prior art. In order to do so, the method comprises deprotonation in a solvent including an alcohol. The invention also relates to an alcohol-containing solution and carbene, and to a solid that can be obtained from the solution, e.g. by means of sublimation.

标 题:Facile synthesis of polyhedral silsesquioxane anions and use thereof
发明人：HASEGAWA ISAO; LAINE RICHARD M; ASUNCION MICHAEL Z; TAKAMURA NORIHIRO
权利人:UNIV MICHIGAN
摘要:Polyhedral silsesquioxane anions are economically prepared by reaction of a silica source derived from combusted organic material with a quaternary ammonium hydroxide compound. Reaction of the resulting anions with chlorosilanes may be effected in near stoichiometric fashion in organic solvent containing reactive quantities of organic acids such as formic acid. The functional groups on the resulting functionalized silsesquioxanes may be substituted for other functional groups by reaction with di- or polysiloxanes in the presence of a synthetic ion exchange resin.

摘要:The present invention belongs to the field of chemistry and chemical engineering, and disclosed are a type of Si-O-Si framework bridged multi-nuclear boron catalyst, a preparation method therefor, and a use thereof. The Si-O-Si framework of the Si-O-Si framework bridged multi-nuclear boron catalyst can be a linear structure of Si-O-Si, a ring structure of Si-O-Si, or a cage structure of Si-O-Si. The feasibility of multiple types of topological structures provides controllability for the synthesis of multi-nuclear boron. The multiple Lewis acid centers of this type of system can better activate monomers and stabilize active species, reflecting the synergistic effect of multiple boron centers. The multi-nuclear boron catalyst of the present invention is mainly used in ring-opening polymerization and copolymerization to prepare diverse low-carbon polymers, such as polyethers, polyesters, polycarbonates, etc.
