1-Bromonaphthalene is an organic compound with the formula C 10 H 7 Br. 1-Bromonaphthalene. It is one of two isomeric bromonaphthalenes, the other being 2-bromonaphthalene. Under normal conditions, the substance is a colorless liquid.
Analogous to the synthesis of phenyllithium is the conversion of 1-bromonaphthalene to 1-lithionaphthalene, by lithium–halogen exchange: C 10 H 7 Br + BuLi → C 10 H 7 Li + BuBr. The resulting lithionaphthalene undergoes a second lithiation, in contrast to the behavior of phenyllithium.
This species reacts with NaOH to give sequentially 1-hydroxynaphthalene-8-sulfonic acid and then the 1,8-diol. [3] Four peri-naphthalene derivatives. Certain perinaphthalene derivatives can be prepared from 1,8-dilithionaphthalene, which in turn is generated by dilithiation of 1-bromonaphthalene: [4] C 10 H 7 Br + BuLi → C 10 H 7 Li + BuBr
1-Naphthoic acid is an organic compound with the formula C 10 H 7 CO 2 H. It is one of two isomeric mono carboxylic acids of naphthalene , the other one being 2-naphthoic acid . In general the hydroxynaphthoic acids are more widely used than the parent naphthoic acids.
1-Chloronaphthalene is an aromatic compound. It is a colorless, oily liquid which may be used to determine the refractive index of crystals by immersion. [ 1 ] The compound is an isomer to 2-chloronaphthalene .
NpP 2 S 4 is a compound related to Lawesson's reagent formed by the reaction of 1-bromonaphthalene with P 4 S 10, [1] this is a 1,3,2,4-dithiadiphosphetane 2,4-disulfide which has a naphth-1,8-diyl group holding the two phosphorus atoms together.
