yields of phosphorus-containing by-products. Similar reactions with 2,3-dichlorobuta-1,3-diene and 2-chlorobuta-1,3-diene give SN2′ rather than direct substitution products. Evidence is presented that adamantene is an initial product in the reaction of lithium diphenylphosphide with 1,2-di-iodo- and 1,2-dibromo-adamantane, but not with 1,2-dichloroadamantane, although 1- and 2-adamantyldiphenylphosphine
Organoarsenic nucleophiles were easily and safely prepared, leading to a practical method for As–C bond formation. Promising ligand structures such as asymmetric and bidentate types can be widely constructed by the present method.
