Zur Regioselektivit�t der Umsetzung von Methallylisothiocyanat mit monosubstituierten Hydrazinen
摘要:
Methallyl isothiocyanate 1 reacts with substituted aryl hydrazines to 1,4- respectively 2,4-disubstituted thiosemicarbazides 4 and 5 in dependence on the reaction conditions and the nature of the aryl group. The influence of the substituents is discussed. The novel N'-mono- and disubstituted N-methallylic thioureas 2 and 3 are synthesized.
