What is the reduction of camphor?

What is the reduction of camphor?

During the reduction of camphor, the reducing agent can approach the carbonyl face with a one carbon bridge (termed exo attack) or the face with a two carbon bridge (termed endo). The two product stereoisomers are called borneol (from exo attack) and isoborneol (from endo attack).

What compounds can be reduced by sodium borohydride?

Sodium borohydride It is only powerful enough to reduce aldehydes, ketones and acid chlorides to alcohols: esters, amides, acids and nitriles are largely untouched. It can also behave as a nucleophile toward halides and epoxides.

What is the relationship between isoborneol and borneol?

An alcohol (borneol) is being oxidized into a ketone (camphor). A subsequent reduction takes us back to another alcohol (isoborneol), which is an isomeric form of the original.

Why was sodium borohydride utilized in the reduction of camphor as opposed to lithium aluminum hydride?

REDUCTION OF CAMPHOR WITH SODIUM BOROHYDRIDE The reduced reactivity of borohydride allows it to be used even in alcohol and water solvents, whereas lithium aluminum hydride reacts violently with these solvents to produce hydrogen gas and thus must be used in nonhydroxylic solvents.

What is the role of methanol in the reduction of camphor?

b. The initial dissolution of camphor favors the reduction of the carbonyl group over the reaction of the sodium borohydride with the the protic solvent, methanol.

Which of the following is not reduced by sodium borohydride?

By itself, it will generally not reduce esters, carboxylic acids, or amides (although it will reduce acyl chlorides to alcohols).

How will you distinguish borneol isoborneol and camphor by GC MS?

How did you identify camphor, borneol, and isoborneol on the GC-MS? On the NMR? Camphor has a different MW, so easier to pick out on the MS. For borneol and isoborneol the library searched the fragmentation patterns.

How do you separate isoborneol and borneol?

Borneol (I) and isoborneol (II) in synthetic Bingpian are separated by means of dry-column chromatography (DCC).

Is borneol or isoborneol more stable?

Though borneol is the more stable product, the energy requirements to form isoborneol are lower because the borohydride is adding to the less sterically hindered point on the carbonyl carbon.
