Siv / Npaj
Siv:
Raws li cov kws tshuaj hauv cov chaw muag tshuaj, {2- pyridoo {} pyridinal tshuaj (xws li cov tshuaj tiv thaiv kab mob antigiral) thiab lwm yam kev sib xyaw ua tshuaj uas muaj pyridine. Cov tshuaj chlorine atoms thiab hydroxyl pawg nyob rau hauv nws cov lwg me me, thiab lub hom phiaj molecules tuaj yeem tsim los ntawm kev hloov pauv xws li nucleophilic hloov thiab txuas ntxiv.
Txoj kev npaj:
- Ib txoj kev hluavtaws ntau yog kom tau 2- pyridoo {2} pyridinecarboxalde nrog hydrogen cov tshuaj chloride. Cov tshuaj tiv thaiv xav tau kev siv ferrous chloride (FECL2) raws li catalyst thiab yog nqa tawm ntawm chav tsev kub.
