A combination catalyst of Pd(dba) 2 ‐PPh 3 ‐CuI‐LiCl or Pd(dba) 2 ‐P(2‐furyl) 3 ‐CuI‐LiCl effectively catalyzed the cross‐coupling of ( Z )‐germyl(stannyl)ethenes with aryl halides, providing novel triethyl(2,2‐diarylethenyl)germanes in good to high yields. The reaction proceeds with retention of configuration. Cross‐coupling results in the formation of phenylene or phenyleneethynylene derivatives with terminal stereochemically defined vinylgermane unit(s). Copyright © 2008 John Wiley & Sons, Ltd.
