实验步骤: A typical procedure is given for the reaction of Entry 1 in Table 1. A 4 mL vial was charged with bromobenzene (63 mg, 0.40, mmol), Pd(dba)2 (11.5 mg, 0.02 mmol), Ph5FcP(t-BU)2 (14.2 mg, 0.02 mmol) and sodium t-butoxide (47 mg, 0.48 mmol). Anhydrous toluene (2 mL) was added, and the vial was sealed with a cap containing a PTFE septum and removed from the drybox. The reaction mixture was stirred at room temperature for 23 h. The reaction solution was then adsorbed onto silica gel, and the product was isolated by eluting with ethyl acetate/hexanes (0 to 10% gradient) to give 58 mg (97%) of t-butoxybenzene. A typical procedure is given for the reaction of Entry 1 in Table 1 the vial was sealed with a cap removed from the drybox the product was isolated by eluting with ethyl acetate/hexanes (0 to 10% gradient)

实验步骤: In this example, phenyl t-butyl ether is prepared. Grignard reagent, phenyl magnesium bromide, is formed by mixing 100 g magnesium turnings with 607.7 g bromobenzene and 6170 g anhydrus ethyl ether. After formation of the Grignard reagent, t-butyl per benzoate (449 g) in ether is added at 15° C.-25° C. under nitrogen with stirring. Reaction product is shaken with cold, dilute hydrochloric acid, then washed with dilue aqueous sodium hydroxide, and then washed with water. It is then dried and distilled to yield 269.2 G of product phenyl t-butyl ether which is analyzed to give 79.1% C (calc 80.0%) and 9.2% H (calc 9.3%). Reaction product washed with dilue aqueous sodium hydroxide washed with water It is then dried distilled
