Structures and reactions of 1,3-diamidodilithium complexes:: the hemisolvated l-[CMe2{CHMeN(R)}2Li2•OEt2], the unsolvated 1:1 mixed organo-amidolithium u-[CMe2{CHMeN(R′)}2•Li2•(nBuLi)2], and the product of oxidative ring closure, the pyrazolidine l-[(RNCHMe)2CMe2] (R=2-iPr-C6H4; R′=2,6-iPr2-C6H3)

摘要：

The hemi-solvated C-2-symmetric 1,3-diamidolithium 1-[CMe2{CHMeN(R)}(2)(Li2OEt2)-O-.] has been crystallographically characterized. It reacts with oxygen to form the N-N ring-closed pyrazolidine 1-[(RNCHMe)(2)CMe2]. The slightly bulkier C-s-symmetric amidolithium u-[CMe2{CHMeN(R')}(2)Li-.(2)] forms an unsolvated 1:2 heterocubane complex with nBuLi in the solid state and in solution, as determined by X-ray crystallography and multinuclear NMR spectroscopy (R = 2-iPr-C6H4; R' = 2,6-iPr(2)-C6H3).
