Summary:The syntheses, properties and NMR data of ether substituted diphosphines, 1,2-bis[bis(methoxyethyl)phosphino]ethane ( 1a) (tmepe), 1,2-bis[bis(methoxypropyl)phosphino]ethane ( 2a) (tpepe) and their quarternary salts, [tmepeH 2] (HSO 4) 2 ( 1b) and [tpepeH 2]Cl 2 ( 2b), are described. The unique role of the phosphonium proton in 1b hydrolytic unstability is discussed.
