Tandem transformations of 1,2,4-triazol-5-ylidenes into 5-amidino-1,2,4-triazoles [PDF]

open access: yesArkivoc, 2007
The first tandem autotransformations of heteroaromatic carbenes have been found. These reactions involve cleavage of the 1-tert-butyl-3,4-diaryl-1,2,4-triazol-5-ylidenes 1a-d to form benzonitriles and the respective carbodiimides, followed by further reactions of the latter with carbenes 1a-d to afford the 3,4-diaryl-5-(1-tert-butyl-3-arylamidin-2-yl ...
