Which functional groups are not reduced by DIBAL.H? According to the table here, diisobutyl aluminium hydride can reduce amides to aldehydes but according to the data given to me by my teacher DIBAL.H cannot reduce:  amides, acids, isocyanides and nitro groups. 

It's I also given in my notes that DIBAL.H is  parallel to $\ce{LiAlH4}$ as a reducing agent but it is more selective. 

I would like to know if DIBAL.H is able to reduce these functional groups or not.
DIBAL-H does the following:

Acid chlorides to aldehydes (Fast)
$3^\circ$ amides to aldehydes
Nitriles to aldehydes
Ketones to $2^\circ$ alcohols
Aldehydes to $1^\circ$ alcohols. (Slower)

Also, it works best in these solvents: THF, toluene.
We need to avoid solvents like alcohols, amines, strong acids and halogenated compounds.
