A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 13440-07-8, Name is Di(naphthalen-1-yl)phosphine oxide, molecular formula is C20H15OP. In a Article，once mentioned of 13440-07-8, Application In Synthesis of Di(naphthalen-1-yl)phosphine oxide
The phosphine, generated together with hydrogen from red phosphorus and aqueous KOH, reacts with 1-bromonaphthalene in the t-BuOK/DMSO system under mild conditions (70 C, atmospheric pressure) to give di(1-naphthyl)phosphine, which is easily oxidized in the presence of air to afford di(1-naphthyl)phosphine oxide in 45% preparative yield. Tri(1-naphthyl)phosphine and naphthalene are also formed in the reaction in 23 and 27% yield, respectively. According to ESR and UV data, the studied phosphination of 1-bromonaphthalene involves a single electron transfer process.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application In Synthesis of Di(naphthalen-1-yl)phosphine oxide. In my other articles, you can also check out more blogs about 13440-07-8
