Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn¡¯t involve a screen. 28244-94-2, C21H26O9S.

A Dinuclear Dysprosium Complex as an Air-Stable and Recyclable Catalyst: Applications in the Deacetylation of Carbohydrate, Aliphatic, and Aromatic Molecules
Two dinuclear DyIII complexes, [Dy2(hmb)2(OTf)2(H2O)4]?HOTf?2 THF (A?HOTf?2 THF) and [Dy2(hmi)3(H2O)2]?2 HOTf (B?2 HOTf), have been synthesized by the reaction of Dy(OTf)3 and the Schiff-base ligands H2hmb (N?-(2-hydroxy-3-methoxybenzylidene)benzohydrazide) or H2hmi ((2-hydroxy-3-methoxyphenyl)methylene isonicotinohydrazine). Disarmed glycosyl trichloroacetimidates can be activated by complex A in the synthesis of 1,2-trans-glycosides with primary and secondary acceptors. This method offers an efficient route to selectively deacetylated monosaccharides and disaccharides in high yields and a green catalyst that can be easily recycled and reused.
