Siv / Npaj
Siv:
Cov tshuaj nruab nrab: 2, {6- dichloro {}} iOdopyridine nyob rau hauv cov synthesis ntawm cov tshuaj tua kab mob. Nws Halogen Atoms tuaj yeem qhia rau lwm pab pawg ua haujlwm (xws li borate thiab amine) los ntawm nucleophilic hloov lossis sib txuas.
Kev tshawb fawb tshawb fawb: Raws li kev tshawb fawb biochemical, nws yog siv rau hauv kev tshawb fawb keeb kwm, piv txwv li cov tshuaj tiv thaiv los koom nrog catalytic cov tshuaj tiv thaiv.
Txoj kev npaj:
- 2 6- Dichhloro -4-}}}}}} iougopyridine 97 feem ntau tau txais los ntawm pyridine iodide thiab cupride chloride thiab cuplous chloride nyob rau hauv cov kuab tshuaj uas haum.
- Cov tshuaj tiv thaiv xav tau kev siv cov tshuaj tiv thaiv uas tsim nyog thiab catalysts thiab feem ntau yog nqa tawm hauv qab kev ua haujlwm hauv inert.
