Question

what is birtch reduction​

Answer 1

Answer:

It's your answer

Explanation:

The Birch reduction is an organic reaction which is particularly useful in synthetic organic chemistry. The reaction was reported in 1944 by the Australian chemist Arthur Birch (1915–1995) working in the Dyson Perrins Laboratory at the University of Oxford,[1][2][3][4][5][6] building on earlier work by Wooster and Godfrey published in 1937.[7] It converts aromatic compounds having a benzenoid ring into a product, 1,4-cyclohexadienes, in which two hydrogen atoms have been attached on opposite ends of the molecule. It is the organic reduction of aromatic rings in liquid ammonia with sodium, lithium or potassium and an alcohol, such as ethanol and tert-butanol. This reaction is quite unlike catalytic hydrogenation, which usually reduces the aromatic ring all the way to a cyclohexane.

Answer 2

Heyaa Dear

Hope it helps:

✏The Birch reduction is an organic chemical reaction where aromatic compounds which have a benzenoid ring are converted into 1,4-cyclohexadiene which have two hydrogen atoms attached at opposite ends of the molecule. It is a very useful reaction in synthetic organic chemistry. The Birch reduction can be classified as an organic redox reaction. Here, an organic reduction of aromatic rings in liquid ammonia with sodium, lithium or potassium and alcohol occurs. An example of a Birch reduction reaction is the reduction of naphthalene.

The Birch reduction is an organic chemical reaction where aromatic compounds which have a benzenoid ring are converted into 1,4-cyclohexadiene which have two hydrogen atoms attached at opposite ends of the molecule. It is a very useful reaction in synthetic organic chemistry. The Birch reduction can be classified as an organic redox reaction. Here, an organic reduction of aromatic rings in liquid ammonia with sodium, lithium or potassium and alcohol occurs. An example of a Birch reduction reaction is the reduction of naphthalene.Birch reduction mechanism begins with the formation of the radical anion by the addition of solvated electrons to the aromatic ring. The alcohol now supplies a proton to the radical anion and also to the next to last carbanion. With the alcohol present, cyclohexadiene and an alkoxide ion are formed as products. The Birch Reduction was first reported by the Australian chemist Arthur Birch in 1944. Arthur Birch was building on the earlier work of Wooster and Godfrey, published in 1937 while he was working in the Dyson Perrins Laboratory at the University of Oxford. Sodium and ethanal were used in the Birch reduction when it was first reported by Arthur Birch. It was discovered that the yield is improved with the usage of lithium. Conjugated enamines can also be formed from the Birch reduction of aniline. Alkynes can also undergo Birch Reduction to form Alkenes .
