Process for the preparation of octafluoro-(2,2) paracyclophane |
摘要 |
A process for the preparation of octafluoro-[2,2]paracyclophane includes contacting a reactant selected from the group consisting of 1,4-bis(bromodifluoromethyl)benzene (dibromide), 1,4-bis(chlorodifluoromethyl)benzene (dichloride), and 1,4-bis(iododifluoromethyl)benzene (diiodide) with trimethylsilyltributyltin (TMSTBT) (a reducing agent) and fluoride ions in a refluxing solution of hexamethylphosphoramide (HMPA) or dimethylsulfoxide (DMSO) in tetrahydrofuran (THF) at conditions effective to promote a reaction product comprising octafluoro-[2,2]paracyclophane.
