The article was titled 《Transition-metal-free approaches to 2,3-diarylated indenones from 2-alkynylbenzaldehydes and phenols with tunable selectivity》, and you may find the article in Chemical Communications (Cambridge, United Kingdom).Safety of 2-Bromonicotinaldehyde The information in the text is summarized as follows:
The first transition-metal-free regioselective synthesis of 2,3-diarylindenones via tandem annulation of 2-alkynylbenzaldehydes with phenols was described. Two different modes of reaction controlled by electronic effects and temperature furnished either “”non-rearranged”” or “”rearranged”” indenones in high selectivity. The experimental process involved the reaction of 2-Bromonicotinaldehyde(cas: 128071-75-0Safety of 2-Bromonicotinaldehyde)
2-Bromonicotinaldehyde(cas: 128071-75-0) belongs to pyridine. Pyridine is widely used in the precursor to agrochemicals and pharmaceuticals. Also, it is used as an important reagent and organic solvent.Safety of 2-Bromonicotinaldehyde
