  摘要：

  已经开发了铑催化的酮与 B2pin2 的脱氧和硼酸化，从而有效地形成烯烃、乙烯基硼酸酯和乙烯基二硼酸酯。这些反应的特点是反应条件温和，底物范围广，官能团兼容性好。机理研究支持酮最初经过 Rh 催化脱氧以通过硼烯醇化物中间体得到烯烃，随后 Rh 催化的烯烃脱氢硼化导致乙烯基硼酸酯和二硼化产物的形成，这也得到 DFT 计算的支持。

  preparation of ketones from carboxylate anions is greatly limited by the required use of organolithium reagents or activated acyl sources that need to be independently prepared. Herein, a specific magnesium amide additive is used to activate and control the addition of more tolerant Grignard reagents to carboxylate anions. This strategy enables the modular synthesis of ketones from CO2 and the preparation

Herein, we extend this methodology to include a bioinspired, catalytic E → Z isomerization of α,β-unsaturated nitriles, thereby mimicking the intermediate Opsin-derived, protonated Schiff base in the visual cycle with simple polarized alkenes. Replacement of the iminium motif by a cyano group is well

  Here, we describe that simple ketones can be efficiently employed as electrophiles in Suzuki-Miyaura coupling reactions via catalytic activation of unstrained C-C bonds. A range of common ketones, such as cyclopentanones, acetophenones, acetone and 1-indanones, could be directly coupled with various arylboronates in high site-selectivity, which offers a distinct entry to more functionalized aromatic

  either (E)- or (Z)-isomers of trisubstituted enamides. Starting from an extensive range of ketones, it was possible to synthesize and isolate the desired pure isomer by switching the reaction conditions. Lewis acid activation enables the formation of the (E)-isomers in high stereoselectivity (>90:10) and good yields. On the other hand, the use of a Brønsted acid allows the preparation of the (Z)-isomers
