- The N-substituents are transferred from the title cations to the C-atom of nitroalkane anions in high yield at 25-80°C in DMSO solution. The title cations are readily available from the appropriate pyrylium cations and primary amines of types RCH2,NH2, and RR'CHNH2, allowing a general 2-step method for the preparation of higher nitro- alkanes. Spectral properties of a variety of nitroalkanes are
-在DMSO溶液中,在25-80°C下,高产率地将N-取代基从标题阳离子转移到硝基烷阴离子的C原子上。标题阳离子可容易地从合适的吡咯鎓阳离子和RCH 2,NH 2和RR'CHNH 2类型的伯胺获得,从而允许使用常规的两步法制备高级硝基烷。讨论了各种硝基烷的光谱性质。
