Abstract
The regiospecific reduction of some triarylpyrylium salts in the presence of modified hydride donors was investigated. Among these reagents, Zn(BH4)2/SiO2performed the best results. The major advantages of this reagent are the cheapness, availability, simplicity in operation, very short reaction time and much improved regioselectivity in comparison with the other reducing reagents.
