Treatment of primary nitro groups, in CH2Cl2 at 0 °C, with Sn(SPh)4, R3P, and DEAD affords quickly and almost quantitatively the corresponding nitriles, in a combined process of deoxygenation and dehydration. The same result can be obtained, although not so rapidly, using only R3P (2 equiv.) and DEAD (1 equiv.).
在0°C下,用Sn(SPh)4,R 3 P和DEAD处理CH 2 Cl 2中的伯硝基,可以在脱氧和脱水的组合过程中快速,几乎定量地得到相应的腈。仅使用R 3 P(2当量)和DEAD(1当量)可以获得相同的结果,尽管不是很快。
