摘要: The condensation of iodobenzene to biphenyl is an industrially important reaction due its significant role in organic synthesis as drug intermediates. takes place the presence copper powder catalyst. We have shown this paper that size nanoparticles well exposed surface area responsible for yield chemical reaction. uncapped showed a 43% conversion 5 h under our experimental conditions. Same amount (size, ∼66 nm diameter) prepared by citrate capping 88% biphenyl, which increased about 95% when 8 diameter capped are used. Surprisingly, no change 95%.
