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。
