Ethene, 1,1-dimethoxy

Analog reagiert Brom-ethen mit 3,3-Dimethoxy-propen und Piperidin bei 100° (20 h) in Gegenwart von Palladium-acetat und Tris-[2-methyl-phenyl]-phosphan zu 5,5-Dimethoxy-1 -piperidim-2-penten (57%)2. [Pg.1228]

Some of the examples where a diazo or a diazonium compound reacts with activated double bonds, specifically with enamines and with 1,2-dimethoxy-ethene have been mentioned in sections 2.1.2 and 2.1.4, respectively (12, 29). A similar reaction is the azo coupling of arenediazonium salts with tropolones (34) The diazonio group reacts at the C-5 atom, so the reaction is used as a diagnostic tool for the presence of substituents at C-5, as well as for the synthesis of 5-amino tropolones by reduction of the azo compound. [Pg.17]

In 3.5 M LiBp4 propylene carbonate/1,2-dimethoxy-ethene, the voltammograms display two peaks, such as in the case of aqueous solutions, the second one at 4.15 V (vs Li/Li ) and the first one around 3.25 V (possibly splitted into two at 3 and 3.35) [94,95]. In Figure 14.38, the differential absorption spectra (relative to the spectrum of the bleached form at low voltage) are given for different potentials. The three absorption maxima are at 2.8, 1.82 and 1 eV. The first voltamogram peak corresponds to the maximum IR absorption, while the second peak conesponds to the... [Pg.775]
