Chen, Ying-Zhe; Ni, Ching-Wen; Teng, Fu-Lin; Ding, Yi-Shun; Lee, Tunng-Hsien; Ho, Jinn-Hsuan published the article 《Construction of polyaromatics via photocyclization of 2-(fur-3-yl)ethenylarenes, using a 3-furyl group as an isopropenyl equivalent synthon》. Keywords: ethenylarene furyl photocyclization; polyaromatic preparation.They researched the compound: 1-(Bromomethyl)-4-ethylbenzene( cas:57825-30-6 ).Electric Literature of C9H11Br. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:57825-30-6) here.
The construction of different types of substituted arenes was demonstrated through the photocyclization of 2-(fur-3-yl)ethenylarenes using a 3-furyl group as an isopropenyl equivalent synthon in the photocyclization reaction. The furan portion of the photocyclization intermediate could be fragmented via a base-induced elimination reaction to yield a series of substituted polyaromatics, including naphthalene, benzofuran, benzothiophene, phenanthrene, phenalene, acenaphthene, and triphenylene. Using different reagents, this method made it possible to introduce Me or 2-hydroxyethyl groups as substituents at specific positions in these arenes.
