“…More recently, the diarsine complex [Rh-(vdiars),+Cl-(vdiars = cis-(C,H,),AsCH= CHAs(C,H,),) (19) was shown to readily undergo a series of reactions involving hydrogen halides, halogens, allyl chloride or methyl iodide to give trans adducts. The complex was found to react reversibly with hydrogen under mild conditions.…”
