Application of 25309-64-2, A common heterocyclic compound, 25309-64-2, name is 1-Ethyl-4-iodobenzene, molecular formula is C8H9I, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: Under nitrogen atmosphere, Cu2O (10 mol %), DABCO (25 mol %), and a stirring bar were added into a 10 mL oven-dried sealed glass tube (as shown in Figure S1). Then NMP (0.5 mL), aryl iodides (0.125 mmol, 1.0 equiv.) and PhSiH3 (0.75 mmol, 6 equiv.) were injected by syringe. The tube was then sealed and CO2 (0.67 mmol, 5.4 equiv., 15 mL) as well as NH3 (0.67 mmol, 5.4 equiv., 15 mL) were injected by syringe after N2 was removed under vacuum. Finally, the mixture was stirred for 24 hr in a pre-heated-to-130 C alloyed block. After the reaction was finished, the tube was cooled to room temperature and the pressure was carefully released. The yield of were measured by GC analysis using dodecane as the internal standard or by flash chromatography on silica gel (petroleumether/ethyl acetate).
The synthetic route of 25309-64-2 has been constantly updated, and we look forward to future research findings.
