Methanesulfonyl chloride/CAS：124-63-0

Ko te Methanesulfonyl chloride he matū kei roto ngā rōpū mahi sulfonyl chloride, e whakamahia whānuitia ana i roto i te hanga i ngā esters waikawa methylsulfonic. He matū tino paitini, he hygroscopic, he waikura, he mea haehae hoki te Methyl sulfonyl chloride. Me rongoa tēnei matū ki te wāhi maroke, pai ake i roto i te whakamaroke. I roto i te whakaputanga ahumahi, ka taea e ia te uru tika ki te tauhohenga rauropi kore utu i waenga i te methane me te thionyl chloride.

Whakamahinga

Ka taea te whakamahi i te Methanesulfonyl chloride hei matū tātari; Ka taea hoki te whakamahi hei whakakorikori mō ngā tauhohenga esterification me te polymerization; Ka taea te whakamahi hei rauemi mata mō te hanga waikawa methanesulfonic; Ka taea te whakamahi whānuitia hei rauemi mata hangai mō ngā rongoā me ngā patupatu; Ka taea hoki te whakamahi hei whakaū mō te hauhā whanariki wai, hei kaihoko chlorinating mō ngā tae whakaiti anthraquinone me te carbazole, hei kaihoko whakamaroke tere mō te whakamaroke i ngā waituhi hinu me ngā paninga, hei whakapai ake i te tae mō te polyester, hei kaiwhakahaere tae mō ngā whakaahua tae, hei kaihoko whakapūmau mō te xylene, te naphthalene me te formaldehyde, me te kaiawhina tae mō te huruhuru hipi.

Ko te whakamahinga matua o te methylsulfonyl chloride ko te whakarite i ngā methylsulfonyl esters mai i ngā waipiro, e hiahia ana kia whai wāhi mai ngā turanga kore-nucleophilic i te wā o te tukanga tauhohenga. Ka taea te whakamahi i ngā methyl sulfonate esters hei takawaenga i roto i ngā tauhohenga whakakapinga nucleophilic, ngā tauhohenga whakakorenga, ngā tauhohenga whakaiti, me ngā tauhohenga whakaritenga anō. Ina rongoatia ki te waikawa Lewis me te oxime, ka taea te methanesulfonate te whakarerekē Beckmann.

I ētahi wā ka taea te whakamahi i ngā esters waikawa methanesulfonic hei rōpū tiaki mō ngā waipiro, e pumau ana i raro i ngā āhuatanga waikawa, ā, ka taea te tango i te parenga mai i te waipiro e te waikawa konutai meruki.

I ētahi wā ka taea te whakamahi i ngā esters waikawa methanesulfonic hei rōpū tiaki mō ngā waipiro, e pumau ana i raro i ngā āhuatanga waikawa, ā, ka taea te tango i te parenga mai i te waipiro e te waikawa konutai meruki.

Ka taea e te methyl sulfonyl chloride te tauhohe ki ngā amine hei hanga i te methyl sulfonamide. He rerekē te methylsulfonyl esters, he rōpū mahi te methylsulfonylamide e tino pumau ana i raro i ngā āhuatanga waikawa me te kawakore. Mēnā ka whakamahia hei rōpū tiaki hei tiaki i te rōpū amino, ka taea te whakamahi i te lithium konumohe tetrahydroxide, te tauhohenga whakaiti whakarewa rewa rānei hei tango i te tiaki.

I te aroaro o te parahi pūhaumāota, ka taea e te methylsulfonyl chloride te tāpiri ki ngā alkynes hei hanga i ngā pūhui β-chlorosulfonyl.
