CO OZNACZA SŁOWO HYDRAZIDE
Hydrazyd
Hydrazydy w chemii organicznej są klasą związków organicznych dzielących wspólną grupę funkcyjną charakteryzującą się wiązaniem kowalencyjnym azotu i azotu z 4 podstawnikami, przy czym co najmniej jeden z nich stanowi grupę acylową. Ogólną strukturą hydrazydu jest R2-N-N-R3R4. Związana z nimi grupa związków zwanych hydrazynami nie ma grupy acylowej. Ważnymi członkami tej grupy są sulfonylohydrazydy, takie jak p-toluenosulfonylohydrazyd, które są użytecznymi odczynnikami w chemii organicznej, takimi jak w reakcji Shapiro. Odczynnik można wytworzyć w reakcji chlorku tosylu z hydrazyną.
Definicja słowa hydrazide w słowniku
Definicja hydrazydu w słowniku jest jedną z klas związków chemicznych, które powstają, gdy wodór w hydrazynie lub którejkolwiek z jego pochodnych jest zastąpiony przez rodnik kwasowy.
