Answer:

The dialdehyde results: #H(O=C)CH(CH_3)CH(CH_3)CH_2CH_2C(=O)H#

Explanation:

#"Diacid + thionyl chloride "rarr" Diacid halide + sulfur dioxide"#

#"Diacid halide + hydride transfer reagent "rarr" Dialdehyde"#

#Li^+[HAl(OBu^t)_3]^-# is a hydride transfer reagent that delivers 1 hydride instead of the 4 that lithium aluminum hydride (#LiAlH_4#) delivers. it will react with acid halides to give the formyl species, the aldehyde:

#"Diacid halide + hydride transfer reagent"# #rarr# #"Dialdehyde + lithium chloride"#
