Yuav ua li cas thaum cawv ua rau TsCl?
TsCl thiab MsCl: Ob Reagents Uas Hloov Hydroxyl Pawg (OH) rau hauv Pab Pawg Zoo. … Kev kho cov cawv nrog TsCl lossis MsCl, feem ntau yog nyob rau hauv lub hauv paus tsis muaj zog xws li pyridine, ua rau sulfonate esters (Lub hom phiaj ntawm pyridine yog txhawm rau tshem tawm cov HCl uas tau tsim thaum lub sijhawm cov tshuaj tiv thaiv.)
Puas yog tosyl chloride yog ib qho zoo nucleophile?
Tosylates yog cov substrates zoo rau kev hloov pauv , reacting nrog nucleophiles ntau tib yam li alkyl halides. … Lub -OH reacts ua ntej raws li ib tug nucleophile, tawm tsam lub electrophilic chaw ntawm tosylate, displacing ib chloride ion, Cl-.
Yuav ua li cas Protonate cawv?
Lub cev qhuav dej feem ntau yog ua los ntawm kev ua kom sov cov cawv nyob rau hauv lub cev muaj zog lub cev qhuav dej, xws li concentrated sulfuric acid.
