日期:2011.5.9
A simple and general copper‐catalyzed method has been developed for transformations of various functionalgroups (I, N3, SO2R, OH, NH2, and NO2) on aromatic rings fromarylboronicacids in water under air. The protocol uses cheap and readily available inorganic salts (KI, NaN3, NaSO2R, NaOH, NaNO2) and aqueous ammonia as the functional‐group sources, simple Cu2O/NH3 as the catalyst system, environmentally
简单和一般铜催化方法已被开发用于各种官能团的变换( I, Ñ 3, SO 2 R, OH, NH 2,和 NO 2)从在水中的芳基硼酸的芳环在空气中。该协议使用廉价且容易获得的无机盐(KI,NaN 3,NaSO 2 R,NaOH,NaNO 2)和氨水作为官能团来源,即简单的Cu 2 O / NH 3。作为催化剂体系,环境友好的水作为溶剂,空气中的氧气作为氧化剂。重要的是,水中的铜催化剂体系是可回收的。该研究应为芳香环上官能团的相互转化提供有用的策略。
Rhodium-Catalyzed Deoxygenation and Borylation of Ketones: A Combined Experimental and Theoretical Investigation
The rhodium-catalyzed deoxygenation and borylation of ketones with B2pin2 have been developed, leading to efficient formation of alkenes, vinylboronates, and vinyldiboronates. These reactions feature mild reaction conditions, a broad substrate scope, and excellent functional-group compatibility. Mechanistic studies support that the ketones initially undergo a Rh-catalyzed deoxygenation to give alkenes

expansion with formation of 2-(dicyanomethylidene)oxazolidine derivatives or creation of the corresponding thiazolidine, imidazolidine, or imidazoline compounds and opens up a new access to these push-pull-substituted olefinic products. The regio- and stereochemistry of the ring-enlargement processes are discussed, and the proposed reaction mechanisms were confirmed by using 15 N-labeled substrates. It
