1-methyl-5-nitro-imidazoles bearing a trisubstituted ethylenic double bond in the 2 position. These compounds are ascribed to a C-alkylation reaction according to the SRN1 mechanism followed by base-promoted nitrous acid elimination.
1-甲基-2-氯甲基-5-硝基咪唑与过量的叔硝酸根阴离子反应,以高收率得到先前未知的1-甲基-5-硝基-咪唑在2位带有三取代的烯键式双键。根据S RN 1机理,将这些化合物归因于C-烷基化反应,然后进行碱促进的亚硝酸消除。
