The aliphatic, phosphine-based pincercomplex [(C10H13-1,3-(CH2P(Cy2)2)Pd(Cl)] (1) is a highlyactiveNegishicatalyst, enable to quantitatively couple various electronically activated, non-activated, deactivated, sterically hindered and functionalized aryl bromides with various diarylzinc reagents within short reaction times and low catalyst loadings. Experimental observations strongly indicate that
