Phosphonium, (bromomethyl)triphenyl-, bromide (1:1) Use and Manufacturing
Triphenylphosphine (15.00 g, 57.25 mmol) and dibromomethane (19.92 g, 114.48 mmol) were dissolved in dried toluene (125 mL), and then the reaction mixture was refluxed for 7 days. After the reaction mixture was cooled to 0 °C, the crystal obtained was filtered and washed with toluene to yield the phosphonium salt (16.50 g, 66percent) as a white solid.Preparation of dibromomethyltriphenylphosphonium (7)
Wittig reagents are used to synthesize bromoalkenes and alkynes from aldehydes.
