Question

rosenmund reaction and friedel craft reaction​

Answer 1

Rosenmund Reaction

❏Rosenmund reduction is a hydrogenation process in which an acyl chloride is selectively reduced to an aldehyde.

❏The reaction was named after Karl Wilhelm Rosenmund, who first reported it in 1918.

Friedel craft reaction

❏The Friedel–Crafts reactions are a set of reactions developed by Charles Friedel and James Crafts in 1877 to attach substituents to an aromatic ring. Friedel–Crafts reactions are of two main types: alkylation reactions and acylation reactions. Both proceed by electrophilic aromatic substitution.

Answer 2

Explanation :

★ Rosenmund Reduction Mechanism. Rosenmund Reduction Mechanism explains the way acyl chlorides are selectively reduced into aldehydes. .

★ The Rosenmund reaction is a hydrogenation process where molecular hydrogen reacts with the acyl chloride in the presence of catalyst – palladium on barium sulfate.
