摘要

Abstract Among the various transition metal chlorides, zirconium (IV) chloride was found to be an efficient catalyst for the rapid synthesis of a wide range of 2, 3-dialkyl-and 2, 3-diaryl- quinoxaline and pyrido [2, 3-b] pyrazine derivatives in excellent yields at room temperature. The remarkable features of this catalytic process are the mild reaction conditions, quantitative yields, short reaction times, high conversions, tolerability of various functional ...
