What are the reaction products between β-hydroxy aldehyde and Grignard reactive? Two products should be formed, one of which (A) is the predominant one



Thanks in advance

Regardless the preparation method, 6-hydroxy-2H-pyran-3(6H)-one is the intramolecular hemiacetal of 5-hydroxy-4-oxo-2-pentenal.
HOCH2COCH=CHCH=O
As a consequence, 6-hydroxy-2H-pyran-3(6H)-one is quickly hydrolyzed to the “mother” compound (5-hydroxy-4-oxo-2-pentenal).
Acetals and hemacetals are instable in acidic medium but relatively stable in neutral and alkaline medium.
So, try to neutralize the medium or alkalize with a little amount of Na2Co3 (if being compatible) and see if you get a better aqueous stability.

Hello best friends
I say you're sorry if I write off-topic
But I just recently had to locate a detailed report about the best ways to create essays to the university.
I just  identified a superb post. Perhaps a person else will have to have this details.

Incidentally, whereas I was trying to find this short article, I discovered that many individuals order household functions, compositions, papers and essays. I do not understand how secure it really is and what high quality can be obtained within the finish. Who faced this concern, write, you create or decide to buy? Were you caught by your tutor for this?

A turbo Grignard reagent is one co-mixed with lithium chloride. A term coined by its discoverer, Paul Knochel, from München.

I think  you mean you want to plate a indium layer not a indium chloride layer.
I would do it by using an electrical plating equipment. Other wise you have only a very thin layer by immersion reaction. With the current and time you can calculate your thickness. Instead of the chloride I would use the sulfate. It depends which kind of anodes you have.

Optimist,

Does the overall complex have a negative charge?

If the final solution has a correct pH and a correct concentration of TEA*, procedure doesn't matter much. Some approaches are easier, some are more difficult, some are safer, but in the end it is the result that counts.

*(note: you have still not addressed the question I asked at the very beginning - 1 M in what should the solution be, it can't be 1 M in "buffer")
