摘要

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.
