This minireview highlights the recent progress made in the last decade towards the development of activated bimetallic alloy nanoparticle catalysts for C–C coupling reactions, including asymmetric C–C bond coupling reactions.

on the occasion of his 54th birthday.Ab imetallic Ni-Pd alloy nanoparticle catalystw ith al ow palladium content (Ni 0.90 Pd 0.10 nanocatalyst)w as prepared and its catalytic performance in Suzuki-Miyaura reactions was evaluated along with that of other Ni-Pd nanocatalysts (with varying Ni/Pd molar ratios in the range of % 0.25-0.75) and the corresponding monometallic, Ni and Pd, analogues.N otably,t he bimetallicN i 0.90 Pd 0.10 alloy nanocatalyst performed exceptionally well for the synthesis of biaryls by employing aw ide range of substituted aryl halidesa nd arylboronic acids having electrondonating and electron-withdrawing groups, and they exhibited high recyclability in water/ethanol solution at moderate reaction temperatures. Catalyst poisoning testsa nd leachinge xperiments inferred the heterogeneousn ature of the Ni 0.90 Pd 0.10 nanocatalysts. The significant synergistic interactions between Ni and Pd accountf or the observed high catalytic efficacy of the Ni 0.90 Pd 0.10 nanocatalyst.At remendous effort has been made towards the development of highly active, selective, stable, and cost-effective catalystsan integral part of any efficient catalytic chemical process. Bimetallicn anocatalysts,a sa lloys or core-shell states, are known to show catalytic performance that is superior to that of its monometallic analogous for many catalytic reactions. [1, 2] The enhanced catalytic performance of bimetallic systemsr esults from favorable synergistic interactions between the metals,f or which strong metal-metal interactions presumably tune the bondingp attern of the reactants and stabilize the important reactionintermediates on the catalyst surface.
