Neodymium, erbium, and europium complexes with 1,6-bis(diphenylphosphoryl)-2,5-dioxahexane (L): The crystal structure of [Nd2(NO3)6L3]

“…Relatively recently, 1,6 bis(diphe nylphosphoryl) 2,5 dioxahexane (L) have been syn thesized through alkylation of lithium glycolates with diphenylchloromethylphosphine oxide. Lithium gly colates have been produced in a separate stage by treating ethylene glycol with butyllithium [8]. The synthesis of this ether with the use of a non aqueous two phase liquid/solid system has also been described in [8].…”

“…Lithium gly colates have been produced in a separate stage by treating ethylene glycol with butyllithium [8]. The synthesis of this ether with the use of a non aqueous two phase liquid/solid system has also been described in [8]. A mixture of KOH and K 2 CO 3 powders was used as the solid phase, and the second phase was a solution of diphenylphosphinic acid and 1,2 bis(chlo romethoxy)ethane in benzene.…”
