专利号:US-7015176-B2 优先权日:2003-06-03 标题 :Process for the synthesis of aryl sulfurpentafluorides 发明人:BAILEY III WADE H; CASTEEL JR WILLIAM J; PESARESI RENO J; PROZONIC FRANK M 权利人:AIR PROD & CHEM 摘要:A process is described for the synthesis of an aryl sulfur pentafluoride compound. In one embodiment of the present invention, there is provided a process for preparing an aryl sulfurpentafluoride compound comprising: combining an at least one aryl sulfur compound with a fluorinating agent to at least partially react and form an intermediate aryl sulfurtrifluoride product; and exposing the intermediate aryl sulfurtrifluoride product to the fluorinating agent and optionally a fluoride source to at least partially react and form the aryl sulfurpentafluoride compound.
