2,4-Dichlorobenzenediazonium tetrafluoroborate CAS:21872-70-8

He matū te 2,4-Dichlorobenzenediazonium tetrafluoroborate e titoa ana i te mowhiti benzene e piri ana ki te rōpū mahi diazonium. Ka whakakapia te mowhiti benzene ki ngā ngota chlorine i ngā tūranga 2 me te 4. Ka tāpirihia te tote tetrafluoroborate hei whakarei ake i te pumau me te wairewa.

He mea whakamahi noa tēnei matū i roto i te hanga matū waro hei ākena hononga diazonium. Ka taea e ia te whai i ngā tauhohenga hononga diazonium me ngā momo matū nucleophilic, pērā i ngā amine, ngā phenols, me ngā nucleophiles waro. Ko ēnei tauhohenga ka hua ake te hanganga o ngā matū kakara, ka taea te whakamahi i roto i ngā tae, ngā pigments, ngā rongoā, me ētahi atu hua matū waro..

Te Whakamahinga me te Pānga

Ngā tauhohenga hononga Aryl: Ka taea te whakamahi i te 2,4-Dichlorobenzenediazonium tetrafluoroborate hei hoa hononga i roto i ngā tauhohenga hononga whakawhiti Suzuki-Miyaura, e āhei ai te hanganga o ngā pūhui biaryl.

Ngā whakakapinga kakara hiko-aroha: Ka taea te whakakapi ngāwari i te rōpū diazonium i roto i tēnei pūhui e ngā nucleophile, pērā i ngā amine, ngā phenol, ngā thiol rānei, ka hua ake te whakaurunga o ngā rōpū mahi rerekē ki ngā mowhiti kakara.

Ngā tauhohenga whānui: Ka taea e te tote diazonium te whakakore i te tangohanga hei hanga i ngā rauropi aryl, ka taea e rātou te whai wāhi atu ki ngā tauhohenga whānui, tae atu ki te hanganga hononga waro-waro..
