초록

Hydrodediazoniation product (3a-d) was found to be the major product in the reaction of arenediazonium tetrafluoroborate (1a-d) with triethylamine (2) in methanol under nitrogen at room temperature. A quantitative study on the title reaction was investigated in detail and two remarks were noteworthy. One was the linear increase in the yield of 3a-d by increasing the molar concentration of 2 until equimolar concentration was reached between 1a-d and 2. The other was the suppression of the formation of 3a-d in the presence of oxygen. Based on these results, the title reaction was better understood by 1:1 electron transfer reaction between reactants (1a-d and 2) rather than by radical chain mechanism proposed in the reaction of arenediazonium tetrafluoroborate and triphenylphosphine.
