Polyphenylene as an electron transfer catalyst in lithiation processes was written by Yus, Miguel;Gomez, Cecilia;Candela, Pablo. And the article was included in Tetrahedron in 2002.Formula: C7H13ClO2 This article mentions the following:
The lithiation of different functionalized chlorinated materials, dichlorinated compounds and benzofused cyclic ethers with lithium powder in the presence of catalytic amounts of either linear (LPP) or crosslinked (CPP) polyphenylene, in THF at temperatures ranging between -78 and 20°C, leads to the expected organolithium intermediates, which by reaction with electrophiles [ButCHO, PhCHO, Et2CO, (CH2)5CO, PhCOMe, Me3SiCl] gives, after hydrolysis with water, the expected products. In the experiment, the researchers used many compounds, for example, 2-(4-Chlorobutyl)-1,3-dioxolane (cas: 118336-86-0Formula: C7H13ClO2).
2-(4-Chlorobutyl)-1,3-dioxolane (cas: 118336-86-0) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Dioxole functionalized metal-organic frameworks have also been recently reported.Formula: C7H13ClO2
