Single crystal X-ray structure of (Z)-1-bromo-1-nitro-2-phenylethene

Abstract

The title compound -(Z)-1-bromo-1-nitro-2-phenylethene -was prepared by a three-step reaction. Its structure was confirmed by spectral analysis as well as X-ray crystallography. It was found, that the compound crystallized in the orthorhombic system, space group Pbca, a=11.5296(6)Å, b=7.5013(5)Å, c=19.7187(12)Å, α=β=γ=90°, Z=8.

Chemistry of 2-aryl-1-cyano-1-nitroethenes. Part I. Synthesis and physical properties

“…The literature describes many methods for the preparation of conjugated nitroalkenes (CNA). Most universal strategies are based on the thermal or catalytic decomposition of nitroalkyl esters [37][38][39][40][41] and dehydrohalogenation of 1,2-dihalo-1-nitroethane derivatives [35,42]. Unfortunately, all these protocols are inadequate for preparation of 2-aryl-1-cyano-1-nitroethenes.…”

Preparation of conjugated nitroalkenes: short review

“…Under catalytic conditions, the one step or stepwise biradical mechanism, is replaced to the stepwise E1CB-like mechanism. This strategy was applied inter alia for the synthesis of 2phenyl-1-bromo-1-nitroethene [60] (Fig. 15.).…”

Novel synthesis scheme and in vitro antimicrobial evaluation of a panel of (E)-2-aryl-1-cyano-1-nitroethenes

“…Product with 90% yield was obtained. Next, (Z)-2-phenyl-1-bromo-1-nitroethene was prepared by dehydrobromination of 2-phenyl-1,2-dibromo-1-nitroethane in the presence of pyridine according to the previously described procedure 16 . ).…”
