Abstract

Reactions of an Al(I) center with Sb–Cl, Bi–Cl and, notably, Sb–H reagents afford a family of Al(III) complexes featuring structurally characterized, pnictogen–halide and –hydride bonds. The Sb–H reaction is particularly striking, simultaneously forging Al–Sb and Al–H bonds to give the first hydridoaluminastibane establishing the previously unknown Al(Sb)(H) functional group. These results introduce pnictogen hydride oxidative addition as a new strategy for Al–Sb bond formation and expands the reactivity landscape of hydrostibination.
