1,1-Diphenylethylene mediates the radical polymerization of methyl acrylate or styrene. Mediation by 1,1-Diphenylethylene generates low molecular weight polymer by a termination reaction. [ 3 ] Additionally, because 1,1-Diphenylethylene has a lower pKa than styrene, it is an effective mediator in the anionic living polymerization of styrene ...
(E)-Stilbene, commonly known as trans-stilbene, is an organic compound represented by the condensed structural formula C 6 H 5 CH=CHC 6 H 5.Classified as a diarylethene, it features a central ethylene moiety with one phenyl group substituent on each end of the carbon–carbon double bond.
Stilbene may refer to one of the two stereoisomers of 1,2-diphenylethene: -Stilbene (trans isomer) ... 1,1-Diphenylethylene This page was last edited on 9 May 2021 ...
Jablonec nad Nisou as viewed across the Mšeno Reservoir. Jablonec nad Nisou is located about 7 km (4 mi) southeast of Liberec and 83 km (52 mi) northeast of Prague. Most of the built-up area lies in the eastern tip of the Zittau Basin, and it is surrounded with the Jizera Mountains in the north, east and south. The northern part of the ...
Diphenylethylene or Diphenylethene may refer to: 1,1-Diphenylethylene; 1,2-Diphenylethylene, or Stilbene (E)-Stilbene (trans-isomer) (Z)-Stilbene (cis-isomer) See also
(Z)-Stilbene is sterically hindered and less stable because the steric interactions force the aromatic rings 43° out-of-plane and prevent conjugation. [2] (Z)-Stilbene has a melting point of 5–6 °C (41–43 °F), while (E)-stilbene melts around 125 °C (257 °F), illustrating that the two compounds are quite different.
Jablonec nad Nisou District is divided into three administrative districts of municipalities with extended competence: Jablonec nad Nisou, Tanvald and Železný Brod.In addition, two municipalities (Jenišovice and Malá Skála) belong to the administrative district of Turnov, which is the only such administrative district in the country whose borders do not correspond to the borders of the ...
Benzil (i.e. Bz 2, systematically known as 1,2-diphenylethane-1,2-dione) is the organic compound with the formula (C 6 H 5 CO) 2, generally abbreviated (PhCO) 2. This yellow solid is one of the most common diketones. Its main use is as a photoinitiator in polymer chemistry. [4]
