Abstract
PURPOSE: To obtain a pyrrole derivative useful as an agricultural chemical or medicine or a raw material for various synthetic chemical reactions utilizing the reactivity thereof, by reacting a trithiocyclopropenium salt with a secondary amine.
CONSTITUTION: A trithiocyclopropenium salt of formula I (R1 is lower alkyl; X is anion) is reacted with a secondary amine of formula II (R2 is alkylene), e.g. azetidine, usually in a suitable solvent, e.g. methylene chloride, at room temperature to 110°C for 30minW1hr to give a pyrrole derivative of formula III. Halogen ions, perchlorate ions or hexafluoroantimonate ions may be cited as X.
