In 2017,Wang, Shao-Bo; Gu, Qing; You, Shu-Li published 《Rhodium(III)-Catalyzed C-H Alkynylation of Ferrocenes with Hypervalent Iodine Reagents》.Journal of Organic Chemistry published the findings.Product Details of 128071-75-0 The information in the text is summarized as follows:
Rapid access to mono- or dialkynylation of ferrocene with ethynylbenziodoxolones as the alkynylation reagents was achieved via Rh-catalyzed direct C-H bond functionalization at room temperature Mono- and dialkynylation were easily modulated by varying the sterical volume of the directing group, such as pyridine and isoquinoline, and amount of hypervalent I reagents. A wide range of ferrocene-based alkynylation products could be obtained in up to 94% yield, and a gram-scale reaction also proceeded smoothly with high efficiency. In the experimental materials used by the author, we found 2-Bromonicotinaldehyde(cas: 128071-75-0Product Details of 128071-75-0)
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.Product Details of 128071-75-0
