suzuki reaction | [reaction suitability]
reaction type: C-C Bond Formation | [Synthesis]
Under nitrogen protection, 280 g of bromobutane and 696 g of triphenylphosphine were added to a 2 L four-neck flask dissolved in 500 mL of xylene. The reaction mixture was heated to reflux temperature with continuous stirring for 6 hours. After completion of the reaction, the system was cooled to room temperature, the precipitated white crystals were collected by filtration and washed with xylene. After drying, 797 g of butyltriphenylphosphonium bromide was obtained as a white solid in 97.7% yield. | [References]
