Also known as 2-Phenylene-bis-dimethylarsine, o-phenylenebis(dimethylarsine), 1,2-phenylenebis(dimethylarsine), diars
1,2-Bis(dimethylarsino)benzene (diars) is the organoarsenic compound with the formula CH(As(CH)). The molecule consists of two dimethylarsino groups attached to adjacent carbon centers of a benzene ring. It is a chelating ligand in coordination chemistry. This colourless oil is commonly abbreviated "diars."

==Coordination chemistry== Related, but non-chelating organoarsenic ligands include triphenylarsine and trimethylarsine. Work on diars preceded the development of the chelating diphosphine ligands such as dppe, which are now prevalent in homogeneous catalysis.
