文摘

⁶Li and ¹⁵N NMR spectroscopic studies of lithium diethylamide (Et₂NLi) solvated by oxetane, THF,and Et₂O are described. Four-, five-, and six-rung ladders, as well as cyclic dimers and trimers, are identified.In addition, dynamic processes within the trimers and ladders are detected. The symmetries of the aggregatesfacilitated the determination of relatively complex solution structures and equilibria.
