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

I-2,4-Dichlorobenzenediazonium tetrafluoroborate yikhemikhali equlathe indandatho yebenzene eqhotyoshelwe kwiqela elisebenzayo le-diazonium. Indandatho yebenzene ithathelwa indawo ngeeathom ze-chlorine kwiindawo zesi-2 nesesi-4. Ityuwa ye-tetrafluoroborate yongezwa ukuphucula uzinzo kunye nokunyibilika.

Le khompawundi isetyenziswa kakhulu kwi-organic synthesis njenge-diazonium coupling agent. Ingadlula kwii-diazonium coupling reactions kunye nee-nucleophilic compounds ezahlukeneyo, ezifana nee-amines, ii-phenols, kunye nee-carbon nucleophiles. Ezi mpendulo ziphumela ekudalweni kwee-aromatic compounds, ezinokuba nezicelo kwiidayi, ii-pigment, amayeza, kunye nezinye iimveliso ze-organic..

Ukusetyenziswa kunye nesiphumo

Iimpendulo zokudibanisa zeAryl: I-2,4-Dichlorobenzenediazonium tetrafluoroborate ingasetyenziswa njengeqabane lokudibanisa kwiimpendulo zokudibanisa zeSuzuki-Miyaura, okuvumela ukwakheka kweekhompawundi zebiaryl.

Izinto ezitshintsha i-electrophilic aromatic substitutions: Iqela le-diazonium kweli qela linokutshintshwa lula zii-nucleophiles, ezifana nee-amines, ii-phenols, okanye ii-thiols, nto leyo ekhokelela ekungenisweni kwamaqela ahlukeneyo asebenzayo kwiiringi ze-aromatic.

Iimpendulo ezingaqhelekanga: Ityuwa ye-diazonium inokususwa ngendlela enciphisayo ukuze yenze i-aryl radicals, enokuthi emva koko ithathe inxaxheba kwiimpendulo ezingaqhelekanga, kuquka ukwakheka kwebhondi ye-carbon-carbon.
