the development of a well-defined Fe catalyst and its application to the regio- and stereoselective 1,4-hydrosilylation of 1,3-dienes. To the best of our knowledge, this is the first example of accessing a characterized low-valent Fe catalyst by controlled reductiveelimination from a readily accessible Fe precatalyst.
我们报告了明确定义的 Fe 催化剂的开发及其在 1,3-二烯的区域选择性和立体选择性 1,4-氢化硅烷化中的应用。据我们所知,这是第一个通过从易于获得的 Fe 预催化剂中受控还原消除来获得表征低价 Fe 催化剂的例子。

The copper-catalyzedcoupling between benzylamino boronate esters and aryl amines has been investigated. Formation of ortho-aminobenzylamines was achieved under oxidative conditions in the presence of copper(II) acetate. The major side product of the transformation is the homocoupling of the aryl boronate ester. The formation of the desired diamines was found to be improved in the absence of base,

benzylic amines with phenols has been achieved to provide biaryl ethers that are prevalent in biologically active compounds. A variety of substitution patterns on the aryl boronate ester and the phenol are tolerated under the reaction conditions, providing moderate to high yields. A competition reaction between phenol and aniline revealed condition-dependent selectivity in which the phenol could be highly

The following organosilver compounds have been prepared from the corresponding lithium compounds and silver bromide : 2-[(dimethylamino)methyl]phenyl}silver, 2-[(dimethylamino)methyl]phenyl}silver·silver bromide, bis[2-(dimethylamino)phenyl]silver} · silver bromide, (2,6-dimethoxyphenyl)silver and (2,4,6-trimethoxyphenyl)silver. These substituted phenylsilvers, which have been characterized by elemental
