Utilisation of a lithium boryl as a reducing agent in low oxidation state group 15 chemistry: synthesis and characterisation of an amido-distibene and a boryl-dibismuthene†
Abstract
The first examples of an amido-distibene, L†SbSbL† (L† = –N(Ar†)(SiPri3), Ar† = C6H2{C(H)Ph2}2Pri-2,6,4), and a boryl dibismuthene, {(DAB)B}BiBi{B(DAB)} (DAB = {(C6H3Pri2-2,6)NCH}2, have been prepared by reaction of a lithium boryl complex, (THF)2LiB(DAB), with extremely bulky amido-group 15 dihalide precursor compounds. In these reactions, the lithium boryl acts as a boryl transfer reagent and/or a strong reducing agent.
