NaY分子筛可促进重氮乙酸乙酯与含吸电子基团的炔烃的1，3-偶极环加成反应，高产率地合成相应的官能化吡唑。通过~(13)C-MAS核磁共振分析，提出了NaY孔内亲偶极分子的活化机制。
Zeolite NaY promotes 1,3-dipolar cycloaddition of ethyl diazoacetate to alkynes having an electron-withdrawing group to afford the corresponding functionalized pyrazoles in high yields. The activation of the dipolarophile inside the pores of NaY is proposed based on the 13 C MAS NMR analysis.
