Khoom Description
Khoom: Zoo:
- Cov tsos mob: 6-Bromo-3,4-dihydro-1(2H)-naphthalenone yog dawb crystalline khoom.
- Solubility: Soluble nyob rau hauv organic solvents xws li ethanol, dimethyl sulfoxide thiab dimethyl formamide, tab sis insoluble nyob rau hauv dej.
6-Bromo-3,4-dihydro-1(2H)-naphthalenone yog cov tshuaj sib xyaw nrog cov mis C8H6BrO. Nws yog tsim los ntawm kev qhib lub nplhaib hauv epichlorohydrin nrog boron trifluoride etherate (BF3OEt2) hauv pyridine ntawm 0 degree. Tom qab ntawd, qhov tshwm sim epoxide yog ua rau hauv tetralin los ntawm kev ntxiv sodium hydroxide. Kev sib xyaw ua ke tuaj yeem ua tiav hauv chav kuaj uas siv cov tshuaj dawb huv thiab ua kom txog li 100% ntawm cov khoom pib rau hauv tetralin. 6-Bromo-tetral-1-ib qho tsis hlawv lossis ua rau cov khoom muaj kuab lom thaum cua sov.

Kev Siv & Kev Npaj
Kev siv:
- 6-Bromo-3,4-dihydro-1(2H)-naphthalenone yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis thiab tuaj yeem siv los tsim ntau yam sib txuas.
- Hauv cov organic synthesis, nws tuaj yeem koom nrog cov tshuaj tiv thaiv nucleophilic hloov pauv thiab cov tshuaj tiv thaiv oxidation.
Txoj Kev Npaj:
6-Bromo-1,2,3,4-tetrahydronaphthalene yog tau los ntawm bromination ntawm naphthalene.
Tom ntej no, 6-bromo-1,2,3,4-tetrahydronaphthalene hloov mus rau 6-Bromo-3,4-dihydro-1(2H)-naphthalenone los ntawm cov tshuaj tiv thaiv oxidation.
