実験手順
A mixture of 1 mol of 3,4,5-trifluorobromobenzene and 3 l of THF is admixed at -70° C. with 1 mol of BuLi. Subsequently, a mixture of 0.5 mol of zinc bromide in 1 l of THF is added to the reaction mixture, and this mixture is stirred for 30 minutes at -65° C. Then 1 mol of vinyl bromide and 0.022 mol of nickel(II) chloride/TPP is added.
後処理
- additionis added to the reaction mixture
