Radul et al. recently reported [1] on the N-alkylation of unsubstituted and sybstituted isatins with a-bromo ketones in benzene and toluene in the presence of bases (pyridine, triethylamine, K2CO3). These reactions led to formation of the correspondi

2-Acylindoles and 2-acylindole-3-carboxylic acids are readily alkylated at the nitrogen atom by haloalkanes in a superbasic medium (DMSO + NaOH). For the carboxylic acids, this reaction may proceed either entirely at the nitrogen atom, or at both the

We have synthesized previously unknown N-vinyltriazoles:1,3-diaryl-3-(1H-1,2,4-triazol-1-yl)-2 propen-1-ones. We discuss a hypothesis for a probable reaction mechanism.
