Rapid Nickel-Catalyzed Suzuki−Miyaura Cross-Couplings of Aryl Carbamates and Sulfamates Utilizing Microwave Heating
摘要:
High-speed and scalable nickel-catalyzed cross-coupling of arylboronic acids with aryl carbamates and sulfamates is achieved by using sealed-vessel microwave processing.
Preparation of reusable copper-based biomass-carbon aerogel catalysts and their application in highly selective reduction of maleimides to succinimides with hydrosilane as a hydrogen source
aerogel construction, and customizable carbonization was designed for the reduction of copper trifluoromethane sulfonate (Cu(OTf)2) to Cu(0) and Cu(I) on the CAC. The Cu(OTf)2@CAC exhibited excellent catalytic activity, chemo-selectivity, and recyclability for selective maleimide reduction to succinimides under mild conditions. Moreover, the Cu(OTf)2@CAC can be reused six times without noticeably losing

Poly (Cs-C9 lactone) modified Mannich base adducts are made by reacting a C5-C9 lactone, an amine, an aldehyde, an N-hydroxyaryiamine, and a hydrocarbyl substituted C4-C10 monounsaturated dicarboxylic acid producing material, e.g., a polyisobutenyl succinic anhydride, which, in turn, preferably is made by reacting a polymer of a C2 to C1 0 monoolefin, preferably polyisobutylene, having a molecular weight of about 700 to 10,000 with a C4 to C10 monounsaturated acid, anhydride or ester, preferably maleic anhydride, such that there are about 0.7 to 2.00 dicarboxylic acid producing moieties per molecule of said olefin polymer used in the reaction mixture. The resulting adducts are useful per se as oil soluble dispersant additives. They are also useful in fuel and lubricating oil compositions, as well as in concentrates and additive packages.

Novel polymers comprising polyolefin-substituted amines grafted with aromatic N-containing monomers such as aniline, have been found to provide oil soluble polymers which have dispersant and antioxidant properties in oleaginous compositions, including fuel and lubricating oils, and also which are useful in electrical applications. These materials are formed by a process which comprises: (a) contacting an amine compound having at least two reactive nitrogen moieties with at least one long chain hydrocarbon-substituted reactant in an amount and under conditions sufficient to form a N-containing polymer adduct containing reactive amine groups, and (b) contacting the N-containing polymer adduct with at least one aromatic N-containing monomer under polymerization conditions to graft said N-containing polymer adduct with aromatic N-containing polymer segments. The long chain hydrocarbon-substituted reactant can comprise materials such as (i) long chain hydrocarbons substituted with mono- or dicarboxylic acid, anhydride or ester groups; (ii) halogenated long chain hydrocarbons; (iii) mixtures of formaldehyde and a long chain hydrocarbyl substituted phenol; and (iv) mixtures of formaldehyde and a reaction product formed by reaction of long chain hydrocarbons substituted with mono- or dicarboxylic acid, anhydride or ester groups and an amino-substituted, optionally hydrocarbyl-substituted phenol.
