Stibine as a reagent in molecular chemistry - Targeted Synthesis of primary and secondary stibanyl-gallanes and their lighter homologues

The reactions of SbH3 with one or two equivalents of (Dipp2NacNac)Ga (Dipp2NacNac = HC{C(Me)N(Dipp)}2; Dipp = 2,6-iPr2C6H3) yield the primary and secondary stibanes (Dipp2NacNac)GaH(SbH2) (3) and {(Dipp2NacNac)GaH}2(SbH) (5). Their lighter homologs were obtained from the analogous reactions with phosphine and arsine. All compounds were characterized using heteronuclear NMR-spectroscopy, IR-spectroscopy and single-crystal X-ray diffraction.
