Biaryl monophosphorus ligands containing a 2,3‐dihydrobenzo[d][1,3]oxaphosphole framework are highly effective for the palladium‐catalyzed Suzuki–Miyaura cross‐coupling reactions of a wide range of substrates. Ligand 1 has demonstrated excellent performance for coupling reactions of extremely hindered arylboronic acids.

A Pd complex with the H‐spirophosphorane ligand, PdCl2P(OCMe2CMe2O)OC6H4NH2} (Cat. 1), was used as the catalyst in the carbonylative Suzukicoupling of substituted iodobenzenes with arylboronic acids and with sodium tetraphenylborate. Substituted diarylketones were obtained in good to excellent yields and a selectivity over 95 % under 1 atm of CO with 1.5 mol % of the catalyst. The promoting role
