The role of [2H]-labelling in the determination of the mechanism of formation of benzyne from benzenediazonium acetate
Abstract
Contrary to a recent report,1 we find that [2H]–[1H] exchange does not occur during the formation of [2H2]- and [2H]-benzynes from [2,4,6-2H3]- and [2-2H]-benzenediazonium acetates in the presence of acetic acid.
