## Abstract Various 1,3βdiarylβ2βarylethynylβ1,3βbutadienes **7** have been prepared by the Pdβcatalyzed trimerization of arylalkynes **4**. Their structures and stereochemistry have been confirmed by Xβray crystal analyses. This procedure provides high regioselectivity to generate adducts __Z__β**
