...A carbon atom adjacent to a carbonyl group is called an α-carbon. Hydrogen atoms attached to these α-carbon centers are called α-hydrogens. Ketones with α-hydrogen centers participate in a so-called keto-enol tautomerism. The reaction with a strong base gives the corresponding enolate, often by deprotonation of the enol. Read full entry

Is there a way to change a Hey everybody, Ive been left
on a cliffhanger after the
first semester of O-Chem. And
this question has been buggin
me for a while. I cant seem to
find the answer in my textbook
so here it is...
I know that if you have, for
example, Cyclohexanol, that
you can make it a ketone with
either Chromic Acid or
Pyridine Chloro Chromate but I
was wondering what can reverse
the reaction. That is, what
can make a Ketone into an
alcohol? Is there a way?
Perhaps something like
nucleophilic substitution or
something?

To change a ketone to an alcohol you need to reduce the ketone. A ketone can be converted by using either sodium borohydride or lithium aluminum hydride in a solution of anhydrous diethyl ether or THF. Lithium aluminum hydride and sodium borohydride reacts with water and alcohols therefore these solvents must be used. Then you would react the products or the reaction with water to form the alcohol. However a majority of the time you will form a secondary alcohol when you reduce a ketone. When you reduce an aldehyde you will form a primary alcohol. |

What could cause elevated Other than diabetes, what
other conditions, factors, or

ketone in the bloodstream?
Excessive starvation is also
not an option.
Thank you for the answer. My
cat is not on the Atkins diet,
but I appreciate your effort.
Thank you Doxy, there is no
alcohol in my home and my cat
is indoor only. The vet is
research the situation with
the university and we hope to
have an answer in the next few
days. Thanks for your
comments, I appreciate them.
This question seemed more of a
medical one then a pet, so I
put it here.

Alcoholic ketoacidosis causes elevated ketones in the bloodstream. It comes from drinking too much alcohol. I sincerely hope this is not an issue with your cat. You may want to consider reposting the question in the Pets section... most of us who hang out over here know only about humans. |
