The invention relates to catalysts allowing for C-C or C-N coupling, their manufacture and use, said catalysts having the formula I wherein (I) R1 and R2 with R3 and R4 and R5 and R6, and the binding atoms are quinolylene; (ii) R3 and R4 with R5 and R6 and R7 and R8, and the binding atoms are naphtylene; (iii) R3 and R4 with R5 and R6 and R7 and R8, and the binding atoms are phenylene, (iv) R5 and R6, with R7 and R8, and the binding atoms are phenylene; or (v) R1 and R2, with R3 and R4, and the binding atoms are pyridylene, while R5 and R6, with R7 and R8, and the binding atoms are phenylene; where the rings may in each case be unsubstituted or substituted; the remaining radicals of R1 to R8 are hydrogen or an organic group; dotted lines in formula I represent absent or present bonds; X is an anionic ligand; and L is a tertiary phosphine moiety.
