About the reaction of aryl fluorides with sodium sulfide: investigation into the selectivity of substitution of fluorobenzonitriles to yield mercaptobenzonitriles via SNAr displacement of fluorine
摘要:
In this report we describe a simple synthesis of mercaptobenzonitriles from the reaction of fluorobenzonitriles with Na2S in DMF at room temperature and following direct treatment with Zn/HCl. Significantly, 2- and 4-fluorobenzonitriles substituted with chlorine or bromine, from the reaction of but not iodine, undergo selective substitution of fluorine at room temperature to yield synthetically useful halo-substituted mercaptobenzonitriles.

4-Mercaptobenzonitrile werden hergestellt, indem man die entsprechenden 4-Halogenbenzonitrile mit Natriumsulfid oder Natriumhydrogensulfid in Gegenwart eines inerten organischen Lösungsmittels umsetzt und anschließend ansäuert. Die so zugänglichen 4-Mercaptobenzonitrile sind mit Ausnahme des unsubstituierten 4-Mercaptobenzonitrils neu und können als Zwischenprodukte zur Herstellung von nematischen flüssig-kristallinen Produkten, Herbiziden und Pflanzenwachtstumsregulatoren verwendet werden.
