Key Points

To explore a ligand-free iridium-catalyzed method for ortho-C-H silylation of arylphosphines.
Used iridium as a catalyst for the reaction.
Employed P(III) direction for selectivity.
Tested various commercial monophosphine ligands with trialkylsilanes of differing properties.
Successfully achieved mild reaction conditions.
Demonstrated broad substrate scope across different ligands.
Illustrated different outcomes based on steric and electronic variations of trialkylsilanes.

Implication

Iridium-catalyzed reactions achieve ortho-C-H silylation in monophosphine ligands, suggesting a modular approach.

Abstract

An iridium-catalyzed, P(III)-directed modular ortho-C–H silylation of commercial monophosphine ligands with readily available trialkylsilanes of varying steric and electronic properties was achieved. This ligand-free strategy exhibits mild condition, broad substrate...
