Trapping reactions with highly unstable hydrides of antimony and bismuth.

(Dipp 2 NacNac)Ga (Dipp 2 NacNac = HC{C(Me)N(Dipp)} 2 ; Dipp = 2,6-iPr 2 C 6 H 3 ) was used as a trapping reagent for the unstable compounds t BuSbH 2 and MeBiH 2 to yield (Dipp 2 NacNac)GaH(SbH t Bu) (1) and {(Dipp 2 NacNac)GaH(BiMe)} 2 (2). Moreover, its reactions with a row of alkylated or arylated dichloro-bismuthenes resulted in either bridged species or the formation of a dibismuthane.
