Pinacol Pinacolone Rearrangement with mechanism and Application

An Acid – catalyzed conversion of polysubstituted ethylene glycols to carbonyl compounds as ketones or aldehydes with elimination of water is known as pinacol or pinacol-pinacolone rearrangement. When 1,2 diols such as 2,3 dimethyl 2,3 butenediol called pinacol on treatment with minarel acid (HCl, H2SO4) they undergo dehydration and rearrangement to form ketone commonly known as … Read more

Fries Rearrangement with mechanism and it’s Application

The Fries rearrangement is an organic reaction which involves the conversion of phenolic esters into hydroxyaryl ketones on heating in the presence of a catalyst Such as HF, AlCl3, BF3 etc. Phenolic esters on heating with aluminium trichloride (Lewis acid) give o and p- acyl phenol. This is known as Fries rearrangement. A mixture of ortho- and … Read more

Beckmann Rearrangement with mechanism

The Beckmann Rearrangement process is an organic reaction that is useful in changing an oxime to that of an amide under some acidic conditions. When Ketoximes on treatment with an acid catalyst undergo rearrangement to give N – substituted amides is known as Beckmann rearrangement. Characteristics:  Anionotropic rearrangement Migration Carbon to electron deficient Nitrogen R & R’ … Read more
