Versuchsvorschrift

A 50 mL of reactor equipped with magnetic stir bar was charged with 186 mg (0.20 mmol) of {[(t-Bu)2P(OH)]2PdCl}2, 1.57 g (10.0 mmol) of bromobenzene, 1.62 g (10.0 mmol) of di-tert-butylphosphine oxide and 1.38 g (10.0 mmol) of K2CO3 in 20.0 mL of 1,4-dioxane. The resulting mixture was refluxed for 23 h to afford di-tert-butylphenylphosphine oxide. 31P NMR (CDCl3, 121 MHz): δ51.9 ppm.
