Intshayelelo

I-Z-Tetrahydro-6-(2-pentenyl)-2H-pyrano-2-enye i-organic compound eneempawu ezilandelayo:

 

Imbonakalo: eqinileyo engenambala okanye etyheli etyheli;

 

Ukusetyenziswa okuphambili kwe-Z-tetrahydro-6-(2-pentenyl)-2H-pyrano-2-enye ngolu hlobo lulandelayo:

 

I-reaction intermediates: njengeziphakathi ezibalulekileyo kwi-organic synthesis, zingasetyenziselwa ukudibanisa ezinye iikhompawundi eziphilayo;

 

Indlela yokulungiselela i-Z-tetrahydro-6-(2-pentenyl)-2H-pyrano-2-enye inokuqhutywa ngamanyathelo alandelayo:

 

I-2-pentenylpyran yayixutywe ne-oxidant ukufumana i-pentene orange ketone.

Ukusabela okongeziweyo phakathi kwe-pentene e-orenji ketone kunye ne-sodium borate kwenziwa ukwenza i-stereoisomers ezimbini: i-Z-tetrahydro-6-(2-pentenyl)-2H-pyran-2-one kunye ne-E-tetrahydro-6-(2-pentenyl)- I-2H-pyrano-2-enye;

I-isomers yahlulwa ukufumana i-Z-tetrahydro-6-(2-pentenyl) efunwayo -2H-pyran-2-enye.

 

Ulwazi lokhuseleko: Uvavanyo oluthile lokhuseleko lwe-Z-tetrahydro-6-(2-pentenyl)-2H-pyrano-2-one kufuneka lubhekiselele kwidatha efanelekileyo yokhuseleko lweekhemikhali. Ngokuqhelekileyo, iikhemikhali kufuneka zigcinwe ngokufanelekileyo, ziphathwe, kwaye zisetyenziswe, kunye nezilumkiso zokuphepha ukudibanisa nolusu, amehlo kunye nephecana lokuphefumla. Nxiba izixhobo zokukhusela ngexesha lokusetyenziswa ukunqanda ukuphefumla umphunga okanye uthuli.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
