An unusual [2+2]-cycloaddition to the C[dbnd]C bond of 1-azadienes has been observed for the first time using the example reaction of 1,3-N-trifluoromethylsulfonyl-1-azabutadienes with carbodiimides. The structure of N-{[2,2-dimethyl-1-cyclohexyl-4-(cyclo

Reported herein is the mechanochemical synthesis of sulfonyl guanidines, a family of molecules which are relevant as pharmaceuticals and herbicides, by direct coupling of sulfonamides and aromatic or aliphatic carbodiimides. Attempts to conduct the coupling in solution have either failed or given very low conversions, thus demonstrating mechanochemistry as the necessary component for the discovery of this synthetic strategy. Milling around: Mechanochemistry is used to develop a method for the direct coupling of carbodiimides and arylsulfonamides using a copper catalyst. Attempts to reproduce this C-N coupling reaction under conventional solution-based conditions either failed or gave very poor conversions.

N-Trifluoromethylsulfonyl-substituted guanidines CF3SO 2N=C(NHR)2 (R = H, cyclohexyl) were synthesized in nearly quantitative yield by reactions of N-sulfinyltrifluoromethanesulfonamide CF 3SO2N=S=O w
