CO OZNACZA SŁOWO DIAZONIUM SALT
Związek diazoniowy
Związki diazoniowe lub sole diazoniowe to grupa związków organicznych mających wspólną grupę funkcyjną R-N2 + X-, gdzie R może stanowić dowolną resztę organiczną taką jak alkil lub aryl, a X oznacza nieorganiczny lub organiczny anion, taki jak atom fluorowca. Sole diazoniowe, zwłaszcza te, w których R oznacza grupę arylową, są ważnymi związkami pośrednimi w syntezie organicznej barwników azowych.
Definicja słowa diazonium salt w słowniku
