please tell me how 3 or 4 molecule of DIBAL are used to reduction of alkyl ester
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.
