Reaction mechanism
« on: April 24, 2012, 07:57:06 AM »
Is there somebody, who can help me with this reaction mechanism? It is two reaction that occur, and those products are used to make up the ketal.

Help you in what way? What is your question?

I would like to know the different step of the specific reaction mechanism.

As far as I can see, all the information is provided in the mechanism you posted. I don't really see how more detail can be added. Perhaps it would be best to review curly arrow notation in your textbook?

Is there a specific step you don't understand or are you struggling with the whole thing?

I am struggling with the whole reaction. I see that I have two reaction, giving mé two products, which react with each other forening a ketal.

I am struggling understand what happens at the different steps. What happens at each step an so on.

Ok, that is a very broad question. The concepts behind curly/curved arrow mechanisms take at least a chapter of a book to explain properly - I don't think the issue you have can be satisfactorily addressed on an Internet forum.

I suggest you look at some organic chemistry textbooks and come back with more specific questions.

I would recommend Reaction "Mechanisms At a Glance: A Stepwise Approach to Problem-Solving in Organic Chemistry - Mark Moloney", but any general organic text will probably be fine to get you started.

This reaction has a simple theme repeated over and over. It has Le Chatelier's Principle. It uses a reagent to absorb the water formed from the carbonyl group.

Why does the carbonyl become protonated?

Why does alcohol attack the carbon of the protonated carbonyl group?
