摘要

The synthesis of Bbp stabilized biradicals of the type [E(mu-NBbp)](2) (E = P, As) (Bbp = 2,6-bis[bis(trimethylsilyl)methyl]phenyl) was investigated. Contrary to the established synthetic protocol for terphenyl substituted biradicals [E(mu-NTer)](2) by reduction of [ClE(mu-NTer)](2), the analogous Bbp substituted precursor [ClE(mu-NBbp)](2) could only be obtained in low yields. For this reason, a new synthesis had to be found to generate [E(mu-NBbp)](2). Instead of using cyclic [ClE(mu-NBbp)](2) we prepared the acyclic Bbp-N(ECl2)(2) species starting from Bbp-NH2 and ECl3 and studied the reduction with magnesium chips, which led to the formation of the desired biradicals [E(mu-NBbp)](2). All species along the reaction path were fully characterized.
