Unsym. imidazolium salts, each having one nitrogen atom (N1) substituted by a cavity-shaped TPR group (TPR = 2,8,14,20-tetrapentylresorcinaren-5-yl), were tested in situ as proligands for the copper-catalyzed allylic arylation of cinnamyl bromide with arylmagnesium halides. The catalytic systems produced mixtures of linear (l) and branched (b) arylated compounds in variable proportions, with the b/l ratio being the highest (78:22) for the most crowded imidazolium salt used, namely that in which the second nitrogen atom (N2) was substituted by a mesityl group (I.–OTf). An N-heterocyclic carbene complex obtained from one of the imidazolium salts was characterized by an X-ray diffraction study. This study involved multiple reactions and reactants, such as Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3Application of 139139-80-3).
Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3) belongs to iodide derivatives. Indole exists overwhelmingly in the 1H-indole form as do other simple indoles. Indole plays a fundamental role for QS in E. coli, being one of the signal molecules responsible for the transcription of a variety of genes (gabT, and tnaB ASTD). Application of 139139-80-3
