Compain, Guillaume; Sikk, Lauri; Massi, Lionel; Gal, Jean-Francois; Dunach, Elisabet published an article in 2017, the title of the article was Bond Strength and Reactivity Scales for Lewis Superacid Adducts: A Comparative Study with In(OTf)3 and Al(OTf)3.Recommanded Product: N,N-Diethylacetamide And the article contains the following content:
Metal triflates, often called Lewis superacids, are potent catalysts for organic synthesis. However, the reactivity of a given Lewis superacid toward a given base is difficult to anticipate. A systematic screening of catalysts is often necessary when developing synthetic methodologies. Presented herein is the development of quant. reactivity and bond strength scales by using mass spectrometry (MS). By applying a collision-induced dissociation (CID) technique to the adducts formed between Lewis superacids Al(OTf)3 or In(OTf)3 with amides bases, including monodentate and bidentate ligands, different dissociation pathways were observed Quant. relative energy scales were established by performing energy-resolved mass spectrometry (ERMS) anal. on the adducts. ERMS of the adducts affords a bond strength scale when the fragmentation leads to the loss of a ligand, and reactivity scales when the dissociation leads to the C-F bond activation of one triflate anion or the deprotonation of the ligand. Al(OTf)3 was found to bind stronger to amides than In(OTf)3 and to provide the most reactive adducts. The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).Recommanded Product: N,N-Diethylacetamide
