These common heterocyclic compound, 766-99-4, name is 1-Ethynyl-4-iodobenzene, 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. 766-99-4
General procedure: A mixture of alkyne 1 (0.25 mmol), sodium sulfinate 2 (0.375 mmol), FeCl3 (20 mol %),K2S2O8 (20 mol %), and water (3 mL) was stirred at rt in an open flask for 6-9 h(Table 2). After completion of the reaction (monitored by TLC), the mixture was extracted with EtOAc (3 5 mL). The combined organic phases were dried over anhyd. Na2SO4, filtered, and concentrated under reduced pressure. The resulting crude product was purified by silica gel column chromatography using a mixture of EtOAc-n-hexane (1:4) as eluent to afford an analytically pure sample of beta-keto sulfones 3 (Table 2).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 766-99-4.
