Haloform reaction
Is it possible to perform a haloform reaction in acidic media? (Its normally done in basic media = hypochlorite solution)
I would think that the hydrolyzation step is slow but does the reaction go all the way to polyhalogenation or does it stop at monohalogenation?
Thanx

I believe that it is the hypohalite ion that performs the nucleofilic attac. A hypohalide acid is not charged and since it is not a strong acid there
shouldnt be so many ions.
hypohalite acids are extremely unstable, can not be synthesised above 5 % conc or so, they decompose into
Cl2 and Cl-
The halogenation goes all the way to a trihalogenation.

I forgot;
adding a strong acid to a hypohalite solution immediately produces halide

Basic Conditions Required
The haloform requires basic conditions. It occurs poorly to a minor degree in neutral conditions, but very well in basic conditions, and hardly at
all, if at all, in strongly acidic conditions.
