4-氯茴香硫醚

反应条件: temp:55.01; pressure:0.00; stir:

实验步骤: dtbpy: A mixture of ortho- and meta-borylated products (102 mg, 71% yield, ortho/meta + para = 2.0); white solid;

反应条件: temp:55.01; pressure:0.00; stir:

实验步骤: Ligand 3f: A mixture of ortho- and meta-borylated products (114 mg, 80% yield, ortho/meta + para = 12); ortho-borylated product 4e was obtained by further purification by GPC (70 mg, 49% yield), white solid (mp. 80-82 oC);

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A 4-necked, 1-liter flask equipped with a stirrer, a thermometer and a condenser tube was charged with 147.0 g (1.00 mole) of 1,4-dichlorobenzene and 67.9 g (0.10 mole) of an aqueous solution of 50 wt % tetra-n-butylphosphonium bromide. 233.6 g (1.00 mole) of an aqueous solution of 30 wt % sodium thiomethoxide was added dropwise at 80° C. over a period of 6 hours. After addition, the mixture was reacted at the same temperature for 10 hours. After completion of reaction, 157.4 g of a crude 1-methylthio-4-chlorobenzene was obtained by separation procedure. A 4-necked, 1-liter flask equipped with a stirrer After addition the mixture was reacted at the same temperature for 10 hours After completion of reaction
