Dehalogenation (original) (raw)
Dehalogenace je označení pro chemické reakce, při kterých dochází k odštěpení halogenu z molekuly. Dělí se na dva druhy: redukční dehalogenaci a dehydrohalogenaci.

| dbo:abstract | Dehalogenace je označení pro chemické reakce, při kterých dochází k odštěpení halogenu z molekuly. Dělí se na dva druhy: redukční dehalogenaci a dehydrohalogenaci. (cs) In organic chemistry, dehalogenation is a set of chemical reactions that involve the cleavage of carbon-halogen bonds; as such, it is the inverse reaction of halogenation. Dehalogenations come in many varieties, including defluorination (removal of fluorine), dechlorination (removal of chlorine), debromination (removal of bromine), and deiodination (removal of iodine). Incentives to investigate dehalogenations include both constructive and destructive goals. Complicated organic compounds such as pharmaceutical drugs are occasionally generated by dehalogenation. Many organohalides are hazardous, so their dehalogenation is one route for their detoxification. (en) Dehalogenacja – reakcja chemiczna eliminacji jednego lub większej liczby atomów z grupy halogenów (fluor, chlor, brom, jod) z cząsteczki związku chemicznego. Przykład: dehalogenacja tetrahalogenoalkanów prowadząca do otrzymania alkinów. Reakcja chlorowcoalkanów z KOH pod wpływem alkoholu prowadzi do odszczepienia się halogenowodoru oraz powstania wiązania podwójnego/potrójnego. Dochodzi też do reakcji dehalogenacji pod wpływem reakcji Grignarda, gdy dwa chlorowce są od siebie oddalone nie więcej niż o cztery węgle. Gdy chlorowce znajdują się przy sąsiednich węglach powstaje wiązanie podwójne, a produktem ubocznym jest dana sól. (pl) |
