Transferreaktionen mit Hilfe von Pb(OAc)4−(CH3)3SiN3, 8. Mitt.

摘要

The behaviour of flexible olefins with the title reagent is studied. By means of the reaction products of isobutylene, 3-cyclohexyl-1-propene and p-allylanisole it is shown that the transfer process can be envisaged as being realized by formally positive azide.Cis- andtrans-butene, cyclohexene and phenylcyclohexene favourcis-addition. A new mechanistic interpretation is presented, which is in accord with earlier results. With styrene derivatives an ambivalent behaviour occurs.
