Unlocking the N2selectivity of benzotriazoles: Regiodivergent and highly selective coupling of benzotriazoles with allenes
The rhodium-catalyzed, highly N2- and N1-selective coupling of benzotriazoles with allenes is reported. The exceptionally high N2 and N1 selectivities were achieved by using a rhodium(I)/DPEphos and rhodium(I)/JoSPOphos catalyst, respectively. This method permits the atom-economic synthesis of valuable branched N2- and N1-allylated benzotriazole derivatives and allows for preliminary studies of their reactivity.
