Title:
ビニルスルホン酸無水物、その製造方法、及びビニルスルホニルフルオリドの製造方法
Document Type and Number:
Japanese Patent JP7044880
Kind Code:
B2
Abstract:
The present disclosure is directed to provide a vinylsulfonic anhydride which is useful as a synthetic intermediate for synthesis of a fluorinated monomer. It is also directed to efficiently produce the vinylsulfonic anhydride. It is further directed to efficiently produce a fluorinated monomer using the vinylsulfonic anhydride. A vinylsulfonic anhydride of the present disclosure is expressed by the general formula (1). Further, a process for producing a vinylsulfonic anhydride of the present disclosure includes making a vinylsulfonic acid compound represented by the general formula (2) come in contact and be mixed with an anhydridization agent. Further, a process for producing a vinylsulfonyl fluoride of the present disclosure includes a step (b) of making a vinylsulfonic anhydride represented by the general formula (1) come in contact and be mixed with a fluorinating agent to prepare a reaction mixture including a vinylsulfonyl fluoride represented by the general formula (3) and a vinylsulfonic acid compound represented by the general formula (2).
