Abstract

An optimised synthesis of 1,1'-bis(2-indenyl)ferrocene in 47% yield from the Pd(0)-catalysed cross coupling between 1,1'-zincated ferrocene and 2-bromo-indene is described along with the formation of (2-indenyl) ferrocene in 40% yield. The analogous synthesis of planar chiral derivatives gave either pure N,N-dimethyl-1-[2-(2-indenyl)ferrocenyl]ethylamine (74%) or-N,N-dimethyl-1-[2,1'-bis(2-indenyl)ferrocenyl]ethylamine (26%) dependent upon the amount of Pd(0) catalyst used.
