Bis(2-methoxyphenyl)phosphine
Bis(2-methoxyphenyl)phosphine (CAS 10177-79-4; C14H15O2P; molar mass 246.24 g/mol), also known as di-o-anisylphosphine, is a secondary aryl phosphine supplied as a low-melting solid (m.p. 86-90 degC). The two ortho-methoxy aryl groups make it a versatile ligand precursor and reactant in organometallic and catalytic chemistry. Tech Serve Solutions supplies it at 97% assay as a research-grade reagent for ligand synthesis, palladium and rhodium catalysis, and related coordination studies.

Phosphine ligand synthesis
As a secondary aryl phosphine bearing two ortho-anisyl groups, it serves as a building block for tertiary phosphines and polydentate ligands. It is reported in the preparation of bis-bidentate tetraphos ligands used to assemble dinuclear palladium(II) complexes.
Rhodium and palladium coordination chemistry
The compound is used to prepare neutral rhodium(I) complexes and related metal complexes, supporting research into homogeneous catalysts and structure-reactivity studies.
Cross-coupling and P-O ligand chemistry
It is employed in Suzuki-Miyaura coupling routes towards alkyl-derivatised phosphine sulfonate (P-O) ligands, which are of interest in palladium-catalysed reactions.
Olefin and CO copolymerisation
Phosphine ligands derived from this reagent feature in CO-ethylene copolymerisation chemistry, where the donor properties of the ligand influence catalyst behaviour.
Allylation of phenols
The reagent is documented as a reactant in the allylation of phenols, illustrating its broader role in synthetic and catalytic transformations.
