Abstract

4 + 2 Cycloaddition Reactions of N‐Sulphinylcarboxamides.

[2+4] and [2+2] Cycloaddition Reactions of N-Sulfinyl Carboxylic Acid Amides with (CF3)2BNMe2. Crystal Structure ofcyclo-(CF3)2B-NMe2-S(=O)-N=C(p-CH3C6H4)-O

“…Formation of six-membered rings by [2ϩ4] cycloaddition of N-sulfinylacylamides is well established in carbon chemistry [4]. For example, vinylbenzene reacts with p-CH 3 C 6 H 4 C(ϭO)-NϭSϭO to form the six-membered [5].…”
