Red phosphorus reacts with 1-bromonaphthalene in the KOH-DMSO system upon heating (47-70°C, 3 h) to give tri(1-naphthyl)phosphane in 10% yield. Microwave activation (600 W, 6 min) of the reaction affords the above-mentioned phosphane in 25% yield.

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.
