Procedure

The same operations as in Example 15 were carried out, except that the amount of copper(I) chloride added was changed to 0.75 g (corresponding to 15% by mol based on the di-tert-butylphosphinous chloride), and after the reaction and the treatment, the solvent and a low-boiling component were distilled off under reduced pressure. As a result, 5.9 g (purity: 93.8%) of tri-tert-butylphosphine was obtained as an oily substance. The yield was 54.4%.
