The present invention pertains to silanyloxyaryl phosphine ligands of formula (I) and their uses with transition metal catalyst precursors for organic synthesis reactions. More particularly, the present invention pertains to the use of silanyloxyaryl phosphine ligands and with transition metal catalyst precursors in C-N cross-coupling reactions.

The new and easily prepared OTips-DalPhos ligand (L1) offers broad substrate scope at relatively low loadings in the palladium-catalyzed C-N cross-coupling/cyclization of o-alkynylhalo(hetero)arenes with primary amines, affording indoles and related heterocyclic derivatives in high yield.
