Alcohols can be prepared from carbonyl compounds such as aldehydes ketones esters acid chlorides and even carboxylic acids by hydride reductions. The most fruitful approach to this end has been to attach alkoxy or alkyl groups on the aluminum. Carbonyl Reduction Wikipedia Primary alcohol is oxi…

Of dibal h are selectively reduced to aldehydes see the explanation above in mechanism section. Carboxylic acids esters and acid halides can be reduced to either aldehydes or a step further to primary alcohols depending on the strength of the reducing agent. Dibal A Bulky Reducing Agent For Este…
