実験手順

2.1 Grams (8.3 mmols) of a 1-bromophenanthrene was dissolved in 43 ml of heptane, 5.3 ml (1.6 mols/l, 8.5 mmols) of butyl lithium was added thereto at room temperature to obtain a 1-lithiophenanthrene, which was cooled down to −5° C., followed by the addition of 2.2 g (5.2 mmols) of the above DBBF. The mixture was stirred for one hour and to which was further added the THF at a temperature of not higher than 0° C. The mixture was stirred at this temperature for 2 hours. The conversion was 99%.
