Polymer supported naphthalene-catalyzed lithiation reactions was written by Gomez, Cecilia;Ruiz, Sonia;Yus, Miguel. And the article was included in Tetrahedron Letters in 1998.Application of 118336-86-0 This article mentions the following:
The reaction of functionalized mono- or dichlorinated materials with an excess of lithium and a catalytic amount of a naphthalene-containing polymer (P-152, easily prepared by radical copolymerization of 2-vinylnaphthalene, styrene and divinylbenzene) in THF either in the presence (Barbier-type conditions) or absence of different electrophiles [Me3SiCl, BuCHO, iso-BuCHO, PhCHO, Et2CO, c(C3H5)2CO, iso-Pr2CO, (CH2)4CO, (CH2)5CO, PhCOMe, PhCH:NPh] leads, after hydrolysis, to the expected products. The catalyst is quant. recovered and can be reused several times without loss of activity. In the experiment, the researchers used many compounds, for example, 2-(4-Chlorobutyl)-1,3-dioxolane (cas: 118336-86-0Application of 118336-86-0).
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. Although benzodioxole is not particularly important, many related compounds containing the methylenedioxyphenyl group are bioactive, and thus are found in pesticides and pharmaceuticals.Application of 118336-86-0
