Versuchsvorschrift

A Boron complex was first created by adding 1-octene (0.744 g, 6.633 mmol) to a stirring solution of 0.5M 9-BBN in THF (13.27 mL, 6.633 mmol). The reaction was left to stir at room temperature overnight. 3M NaOH (2.34 mL) was then added to the stirring solution followed by the addition of 5-Bromo-indan-1-one (1 g, 4.7 mmol) and Pd(Ph3)4 (0.145 g, 0.126 mmol). The reaction was refluxed for twelve hours. The resulting solution was concentrated and purified using silica gel chromatography eluding with hexanes-EtOAc (9:1). The reaction provided 2 (1.094 g, 4.48 mmol, 95%) as a clear liquid.
