Hydrovinylation, reviews

The transition metal-catalyzed hydrovinylation has been reviewed by RajanBabu who focused mainly on asymmetric reactions, affording chiral compounds.146 The vinylarenes are the most investigated substrates for the hydrovinylation reaction due to the high appeal of the final products in medicinal or polymer chemistry fields.1... [Pg.318]

Similarly, asymmetric metal-catalyzed hydrovinylation of various other olefins has been investigated, usually catalyzed by nickel systems prepared from Ni(IJ) salts or / -allylnickel halides, activated by Lewis acids such as ethylaluminum dichloride or diethylaluminum chloride, and modified by chiral phosphanes. Surveys of these results are found in more general reviews11-12 and reviews dealing preferentially with this subject -5-7-13 - A... [Pg.295]

Palladium-catalysed hydroarylations and hydrovinylations of olefins and acetylenes have been reviewed. Vinyl iodide, for instance, reacts with internal acetylenes in the presence of (PPh3)2Pd(OAc)2, triethylamine and formic acid to yield the alkenes 204... [Pg.311]

In 2009, Yu and co-workers wrote a comprehensive review on diastereo-selective and enantioselective C—H bond functionalization by transition metal catalysts, which presented the historical retrospective of this area in an elegant manner. Therefore, in the following sections, we will focus on the discussion of the latest achievements on the catalytic asymmetric C—H bond functionalization via a transient C—M bond (mainly contributions after 2009). The reactions will be classified according to the metal catalyst as well as the mechanistic scenario. Note that asymmetric hydroacylation and hydrovinylation, two important kinds of methods for the functionalization of aldehyde and alkene C—H bonds, will be covered in two separate chapters of this book (Chapters 8 and 9). [Pg.142]
