with aroyl chlorides, catalysed by palladium(II) acetate, leads to styrene and stilbene derivatives. By appropriate choice of reaction conditions, particularly the ethylene pressure, the reaction can be made to produce either styrene or stilbene derivatives selectively. The reaction tolerates those common substituents which do not react with aroyl chlorides. Only trans-stilbene derivatives are formed

A novel copper‐catalyzed intermoleculartrifluoromethylazidation of alkenes has been developed under mild reaction conditions. A variety of CF3‐containing organoazides were directly synthesized from a wide range of olefins, including activated and unactivated alkenes, and the resulting products can be easily transformed into the corresponding CF3‐containing amine derivatives.

A highly Markovnikov-selective, iron-catalyzed hydroboration of styrenes is reported using available oxazolinylphenyl picolinamide as the ligand to afford the branched hydroboration products with up to >50/1 b/l. This reaction is operationally simple and could be carried out in gram scale.
据报道,使用可用的恶唑啉基苯基吡啶甲酸酰胺作为配体,对苯乙烯进行了高度马尔科夫尼科夫选择性铁催化的硼氢化反应,以提供最高> 50/1 b / l的支链硼氢化产物。该反应操作简单,可以以克为单位进行。
Cobalt(II)‐Catalyzed Bisfunctionalization of Alkenes with Diarylphosphine Oxide and Peroxide
The low‐cost cobalt(II) catalyst has been used for the first time to achieve P(O)‐radical‐mediated bisfunctionalization of alkenes with diarylphosphine oxide and peroxides. This simple process is performed under mild conditions to afford a wide variety of phosphonation‐peroxidation products in a one‐pot manner. Computational studies are carried out to provide a theoretical support for the P(O)‐radical‐involved

An effective Pd-catalyzed regio- and enantioselective hydroesterification of aryl olefins with phenyl formate is described. A variety of phenyl 2-arylpropanoates can be obtained in good yields with high b/l ratios and ee’s without using toxic CO gas.
