Abstract

Since metal nanoparticles have a high surface-to-volume ratio and very active surface atoms, they are very attractive catalysts for a wide variety of organic and inorganic reactions, compared to bulk catalysts. Metal nanoparticles suspended in colloidal solutions and those adsorbed onto bulk supports have been used as catalysts for a wide variety of carbon-carbon bond formation reactions such as the Suzuki and Heck cross-coupling reactions. This review article highlights some of the latest advances in the application of noble metal nanoparticles as catalysts for these two industrially important classes of cross-coupling reactions. We will discuss several important advances in using metal nanocatalysts in Suzuki and Heck cross-coupling reactions such as investigations on the nanoparticle shape dependence on the catalytic activity, novel types of supported metal nanoparticles as nanocatalysts, and the use of bi-metallic, tri-metallic and multi-metallic nanoparticles as catalysts for the Suzuki and Heck cross-coupling reactions.

Highlights

Introduction to the Suzuki and HeckCross-Coupling ReactionsSuzuki cross-coupling reactions, which are referred to as Suzuki-Miyaura reactions [1,2,3], involve the cross-coupling of organoboronic acids with aryl halides to form biaryls [3]
We focus on the recent advances that have been made in the following three areas: nanoparticle shape dependence on the catalytic activity, novel types of supported metal nanoparticles as nanocatalysts, and the use of bimetallic and multi-metallic nanoparticles as catalysts
The above studies have opened up many possibilities of synthesizing noble metal nanoparticles of different shapes and testing their catalytic activity for different types of cross-coupling reactions

The above studies have opened up many possibilities of synthesizing noble metal nanoparticles of different shapes and testing their catalytic activity for different types of cross-coupling reactions. There have been some important studies in which noble metal nanoparticles of different shapes have been used as catalysts for Suzuki cross-coupling reactions.
