Arylations of non-Substituted Trialkylvinylsilane
Typical Procedure:
A THF solution of TASF (1.0 M solution, 0.40 mL, 0.40 mmol) is added to trimethylvinylsilane (40 mg, 0.40 mmol) and allylpalladium chloride dimer (2.7 mg, 0.0075 mmol) dissolved in HMPA (0.3 mL) at 0 °C under an argon atmosphere. 1-Iodonaphthalene (76 mg, 0.30 mmol) is injected to the resulting solution, and the mixture is stirred at 50 °C for 2 h. After completion of the reaction, the bulk of the solvent is removed by passing the reaction mixture through a silica gel column with pentane as the eluent. Evaporation of the pentane under reduced pressure gives pure 1-vinylnaphthalene (42 mg, Y. 98%).
