Some common heterocyclic compound, 355-43-1, name is 1,1,1,2,2,3,3,4,4,5,5,6,6-Tridecafluoro-6-iodohexane, molecular formula is C6F13I, 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. Safety of 1,1,1,2,2,3,3,4,4,5,5,6,6-Tridecafluoro-6-iodohexane
A Schlenk flask was charged with alkoxy ester 10b (3.48g, 10.0mmol), copper powder (1.40g, 22.0mmol), 2,2?-bipyridyl (20mg, 0.13mmol), DMSO (40mL) and hexafluorobenzene (80mL). The mixture was heated to 70C and perfluorohexyl iodide (4.47g, 22.0mmol), dissolved in hexafluorobenzene (20mL), was dropwise added. The mixture was then heated to 105C for 72h. After cooling to r.t., the mixture was partitioned between water (60mL) and dichloromethane (60mL) and the heterogeneous mixture formed was filtered over short silica gel column. The organic layer was separated and the aqueous layer was extracted with dichloromethane (3¡Á60mL). The combined organic layers were dried with anhydrous magnesium sulfate, the drying agent was filtered off and the solvent was removed on a rotary vacuum evaporator (40C, 1h, 25kPa) to give the target ester 11b (5.19g, 95.9%, colourless viscous oil).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 355-43-1, its application will become more common.
