A series of novel linked indolyl phosphine ligands for transition metals, the synthesis thereof and their use in catalytic coupling reactions are provided. The ligands provide improvements of trasition-metal-catalyzed reactions, including the range of substrates scope, reaction conditions and efficieny.

Expanding the horizons of ArPPh2: New applications of triarylphosphane ligands are presented. The Pd–L1 and Pd–L2 complexes offer exceptionally high activity in Suzuki–Miyaura cross‐couplings of aryl chlorides. The extremely congested synthesis of tetra‐ortho‐substituted biaryl compounds is achieved for the first time by simply using triarylphosphane ligands.
