Versuchsvorschrift

Chlorocyclohexane (59.5 mg, 0.5 mmol) and a THF solution (0.77 mL, 0.97 M, 0.75 mmol) of phenylmagnesium bromide were used as starting materials, and reacted as in Entry 1. Conditions: The THF solution of phenylmagnesium bromide was added dropwise at 40° C. over 2 hours. 1H-NMR analysis was conducted using pyrazine (19.4 mg, 0.24 mmol) as an internal standard (yield 85%).
