give me detailed mechanism

what’s the meaning of Me on this diagram?

Me means “methyl”, or CH3

Hey, will lithium tri-tert-butoxyaluminum hydride work here, as well, or just for the acid halides? If not, why the selectivity?
Thanks in advance!

Yep – it will also reduce aldehydes. That’s why it’s important to use only 1 equivalent when reducing acid halides, otherwise you get full reduction to the alcohol.
