Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Tri(naphthalen-1-yl)phosphine, is researched, Molecular C30H21P, CAS is 3411-48-1, about Reaction of 1-bromonaphthalene with PH3 in the t-BuOK/DMSO system: PCl3-free synthesis of di(1-naphthyl)phosphine and its oxide.Formula: C30H21P.
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, atm. 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, resp. According to ESR and UV data, the studied phosphination of 1-bromonaphthalene involves a single electron transfer process.
