Question

Explain the wittig reaction mechanism.

Answer 1

the wittig reaction mechanism is an organic reaction used to convert a primary or secondary alkyl halide and an aldehyde or ketone to an olefin using triphenylphosphine and base.

Answer 2

Explain the wittig reaction mechanism.

The Wittig reaction or olefination is a chemical reaction of an aldehyde or

ketone with a tripheyl phosphonium ylid to given an alkene and

triphenylphosphine oxid .the wittig reaction was discovered in 1954 by

Georg wittig for which he was awarded the Nobel prize in chemistry in

1979. the wittig reaction is useful method for synthesis of alkenes by

treatment of aldehyde or ketone with alkylidenetriphenyl phosphorane

(CKA; phosphorane ph3P=CR2)

The Wittig Reaction ;

Ph3P=CH2+Ph2C=o=====⇒Ph2C=CH2+Ph3P=o
