zinc/hydrazine hydrate as a new reduction system, polyfluoroalkyl halides such as Cl(CF2)nH (1a–c, n = 4, 6, 8), Cl(CF2)nI (1e, n=4, 6, 8) and R(CF2)nCl (n = 4, 6, 1h,i) have been converted to the corresponding reduction products H (CF2)nH (2a–g, n = 4, 6, 8) and R(CF2)nH (n = 4, 6, 2h, i) in high yield. Reduction of the CF2C1 group was faster than that of the CHI in the reaction of 1m.
使用水合锌/肼作为新的还原系统,多氟烷基卤化物如Cl(CF 2)n H(1a–c,n = 4,6,8),Cl(CF 2)n I(1e,n = 4, 6,8)和R(CF 2)n Cl(n = 4,6,1h,i)已转换为相应的还原产物H(CF 2)n H(2a–g,n = 4,6,8 )和R(CF 2)n H(n = 4,6,2h,i)高产。在1m反应中CF 2 C1的还原速度比CHI快。
