Bis(chlorogold(I)) bis(diphenylphosphino)methane
Bis(chlorogold(I)) bis(diphenylphosphino)methane (CAS 37095-27-5; C25H22Au2Cl2P2; molar mass 849.23 g/mol) is a dinuclear gold(I) phosphine complex in which two chlorogold(I) centres are bridged by bis(diphenylphosphino)methane (dppm). Supplied at 97% assay, it is a defined organometallic reagent used principally as a precursor and precatalyst in homogeneous gold catalysis and in the study of metallophilic gold-gold interactions. Tech Serve Solutions supplies it for research and synthetic applications.

Homogeneous gold(I) catalysis
Serves as a gold(I) source and precatalyst in homogeneous catalysis, where digold species and dppm-supported gold centres are explored for activation of alkynes, allenes and related unsaturated substrates. Catalytic activity is typically developed through halide abstraction or ligand exchange.
Dinuclear and cluster gold chemistry
The bridging dppm ligand holds two gold(I) atoms in close proximity, making this complex a useful building block for dinuclear, polynuclear and gold-cluster compounds in coordination and organometallic research.
Aurophilicity and photophysical studies
Widely used to investigate gold(I)-gold(I) (aurophilic) interactions and the luminescent behaviour they produce, of interest in fundamental bonding studies and the design of phosphorescent gold materials.
Organometallic synthesis precursor
The labile gold-chloride bonds allow straightforward substitution, providing a versatile entry point to a range of dppm-bridged gold(I) derivatives and related complexes.
