organic chemistry - Reactions of phloroglucinol

Does phloroglucinol respond to the

• iodoform test?


• cerric ammonium nitrate test?


• 2,4-DNP test?

I couldn't find any good sources that answer any of these.

I thought of this:

1. 
   

   Tautomerism can "change" phloroglucinol to a 1,3,5-triketone, which should respond to the iodoform test.

   
   


2. 
   

   It is a phenol, so it should respond to the cerric ammonium nitrate test.

   
   


3. 
   

   Again, the keto form should respond positively to the dinitrophenylhydrazine test.
