Kojima, Akihiko published the artcileSynthesis and evaluation of a new chiral arsine ligand; 2,2′-bis(diphenylarsino)-1,1′-binaphthyl (BINAs), Quality Control of 126613-06-7, the publication is Tetrahedron Letters (1997), 38(19), 3459-3460, database is CAplus.

Chiral 2,2′-bis(diphenylarsino)-1,1′-binaphthyl [(R)-BINAs] was prepared in 34% yield by reaction of Ph2AsH with (R)-binaphthol ditriflate in DMF containing 10 mol % Ni(COD)2-dppe. BINAs was an effective ligand in the asym. Heck cyclization of alkenyl iodide I (R = OSiMe2CMe3) when 5 mol % Pd2(dba)3 was used as catalyst; 90% chem. yield of tetrahydronaphthalene II was obtained with 82% ee.
