Succinonitrile Activated by Thiating Agents as Precursor of Bis-cyclic Amidines,Tectons for Molecular Engineering

摘要

Modification of the thio-Pinner's method via in situ activation of a nitrile by thiating agents,S8,P4S10,Lawesson reagent,or Na2S · 9H2O,was applied in the syntheses of bis(4,5-dmydro-1H-imidazol-2-yl)alkanes and bis(1,4,5,6-tetrahydropyrimidin-2-yl)alkanes.
