Veerakanellore, Giri Babu published the artcileSolid-state photochemistry of cis-cinnamic acids: a competition between [2+2] addition and cis-trans isomerization, Recommanded Product: (E)-3-(2,4-Dimethoxyphenyl)acrylic acid, the publication is CrystEngComm (2016), 18(25), 4708-4712, database is CAplus.
With three examples, we have established that cis-cinnamic acids can dimerize via a diradical intermediate in the crystalline state provided that the intermol. distance is less than 4.2 ?. In the excited state of cis-isomers, C-C bond formation with an adjacent mol. competes with geometric isomerization.
CrystEngComm published new progress about 16909-09-4. 16909-09-4 belongs to catalysis-chemistry, auxiliary class Alkenyl,Carboxylic acid,Benzene,Ether, name is (E)-3-(2,4-Dimethoxyphenyl)acrylic acid, and the molecular formula is C13H10O2, Recommanded Product: (E)-3-(2,4-Dimethoxyphenyl)acrylic acid.
