Photolysis of cis-Hexene-2 and cis-Butene-2 at 2026 and 2062 A

LINEAR ALIPHATIC UNSATURATED POLYESTERS BASED ON CIS -2- BUTENE -1,4-DIOL: SYNTHESIS AND CHARACTERIZATION

A new homologous series of linear aliphatic polyesters, such as poly (cis-2- butenylene carboxylate)S, PBms (m is the number of methylene groups in the acid component, m=2-8 have been synthesized by direct polyesterification reactions in anisole, as solvent. FT-IR, 400 MHz H- NMR, C-NMR and elemental analysis were used to establish the structure of polyesters. Molecular weight distributi...

Isomerization and Hydrogenation of cis-2-Butene on Pd Model Catalyst

The adsorption and kinetics of conversion of cis-2-butene with deuterium on model supported Pd catalyst (Pd/Fe3O4/Pt(111)) were characterized by reflection-absorption infrared spectroscopy (RAIRS), temperatureprogrammed desorption (TPD), and isothermal molecular beam (MB) experiments. It was found that selectivity toward cis-trans isomerization and hydrogenation depends critically on the nature...

Detection of DNA adducts derived from the reactive metabolite of furan, cis-2-butene-1,4-dial.

Furan is a toxic and carcinogenic compound used in industry and commonly found in the environment. The mechanism of furan's carcinogenesis is not well-understood and may involve both genotoxic and nongenotoxic pathways. Furan undergoes oxidation by cytochrome P450 to cis-2-butene-1,4-dial, which is thought to mediate furan's toxic effects. Consistently, cis-2-butene-1,4-dial readily reacts with...
