The synthesis of 3,3-dimethylmorpholine-2,5-diones 4a was achieved conveniently via the direct amide cyclization of the linear precursors of type 3, which were prepared by coupling of 2,2-dimethyl-2H-azirin-3-amines 2 with 2-hydroxyalkanoic acids 1. Thionation of 4a with Lawessons reagent yielded th

The reaction between Nd(AsF 6 ) 3(solv) and excess of XeF 2(solv) in anhydrous HF (aHF) yields compounds of the type [Nd(XeF 2 ) n ] (AsF 6 ) 3 (n β«Ψβ¬ 3, 2.5). The 5rst compound is very soluble in aHF while the latter crystallizes from the saturated solution in aHF. Pink needles [Nd(XeF 2 ) 2.5 ] (A
