## Abstract A novel chelated ferrocene‐based planar chiral N‐heterocyclic carbene‐Rh(I) complex was synthesized by a simple method. It was applied to the asymmetric transfer hydrogenation of prochiral ketones. Enantioselectivities of up to 67% ee were observed. Copyright © 2009 John Wiley & Sons, L
on the occasion of his 65th birthday The Suzuki cross-coupling reaction, which involves the coupling of aryl boronic acid with an organohalide, has proven to be a versatile tool in organic synthesis. [1] Recent developments have led to catalysts based on sterically demanding, basic phosphanes allow
