YieldReaction ConditionsOperation in experiment
80% With palladium diacetate; copper 8-hydroxyquinolinate; triethylamine; [5-(diphenylphosphanyl)-9,9-dimethyl-9H-xanthen-4-yl]diphenylphosphane In toluene at 140℃; A 1000 mL autoclave was charged with 60 g of 2-bromo-5-phenoxybenzyl alcohol (Compound 3), 300 g of toluene, 30 g of triethylamine, and 30 mg of palladium acetate.150 mg of 4,5-bisdiphenylphosphine-9,9-dimethylxanthene and 0.9 g of 8-hydroxyquinoline copper, cover the kettle lid, vacuum replacement three times; pass carbon monoxide gas to a pressure of 1.0- 1.5MPa, heat up to 140°C,The reaction was maintained until the starting 2-bromo-5-phenoxybenzyl alcohol (Compound 3) was < 3percent. The reaction is over,The material was cooled to room temperature, carbon dioxide was replaced with nitrogen and 200 g of water was added.The resulting triethylamine hydrobromide was dissolved by stirring. 10g of cellulose was added to the reaction material and stirred for 1 hour. The insoluble matter was removed by filtration; the filtrate was allowed to stand and stratified, and the aqueous layer was discarded.The organic layer was washed with 5percent hydrochloric acid until acidic. Organic layer decompression recovery of toluene,Add 200g of methanol to the residue and warm it up to 60-70°C to dissolve the solid.Then add 5g of activated carbon to decolorize for 30 minutes;The filtrate was slowly cooled to 0-5°C to crystallize. The solid obtained was filtered and dried at 60° C. under atmospheric pressure to give 5-phenoxyphenylhydrazine (Compound 1) as a product with a yield of 80percent and a purity of 99.53percent.
