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

I-2,4-Dichlorobenzenediazonium tetrafluoroborate iyinhlanganisela yamakhemikhali equkethe indandatho ye-benzene exhunywe eqenjini elisebenzayo le-diazonium. Indandatho ye-benzene ithathelwa indawo ngama-athomu e-chlorine ezindaweni 2 no-4. Usawoti we-tetrafluoroborate uyangezwa ukuze kuthuthukiswe ukuzinza nokuncibilika.

Le nhlanganisela ivame ukusetshenziswa ekwakhiweni kwezinto eziphilayo njenge-ejenti yokuhlanganisa i-diazonium. Ingabhekana nokusabela kokuxhuma kwe-diazonium nama-compound ahlukahlukene e-nucleophilic, njenge-amine, ama-phenol, nama-carbon nucleophiles. Lokhu kusabela kuphumela ekwakhekeni kwama-compound aromatic, angaba nokusetshenziswa kudayi, ama-pigment, imithi, kanye neminye imikhiqizo yemvelo..

Ukusetshenziswa kanye Nomphumela

Ukusabela kokuxhumanisa kwe-Aryl: I-2,4-Dichlorobenzenediazonium tetrafluoroborate ingasetshenziswa njengomlingani wokuxhumanisa ekusabela kokuxhumanisa kwe-Suzuki-Miyaura, okuvumela ukwakheka kwama-compound e-biaryl.

Ukushintshaniswa kwe-aromatic okufana ne-electrophilic: Iqembu le-diazonium kulesi sakhi lingashintshwa kalula yi-nucleophiles, njenge-amines, i-phenols, noma i-thiols, okuholela ekungenisweni kwamaqembu ahlukahlukene asebenzayo ezindongeni ze-aromatic.

Ukusabela Okukhulu: Usawoti we-diazonium ungasuswa kancane kancane ukuze wakhe ama-aryl radicals, angabe esebamba iqhaza ekuphenduleni Okukhulu, okuhlanganisa ukwakheka kwesibopho se-carbon-carbon.
