N-Trimethylsilyl-bis(trifluoromethanesulfonyl)imide: a better carbonyl activator than trimethylsilyl triflate

N-trimethylsilyl-bis(trifluoromethanesulfonyl)imide (TMSNTf2) was readily prepared from allyltrimethylsilane and bis(trifluoromethanesulfonyl)imide. It was shown to complex carbonyl groups much more effectively than trimethylsilyl triflate. As a result, TMSNTF2 was found to be superior to TMSOTf as a catalyst for the Diels-Alder reaction of methyl acrylate with various dienes.

N-三甲基甲硅烷基双(三氟甲磺酰基)酰亚胺:比三氟甲磺酸三甲基甲硅烷基酯更好的羰基活化剂

N-三甲基甲硅烷基-双(三氟甲磺酰基)酰亚胺(TMSNTf 2)易于从烯丙基三甲基硅烷和双(三氟甲磺酰基)酰亚胺制备。与三氟甲磺酸三甲基甲硅烷基酯相比,它能更有效地络合羰基。结果,发现TMSNTF 2作为用于丙烯酸甲酯与各种二烯的Diels-Alder反应的催化剂优于TMSOTf。
