Talk:Grignard reaction

From Wikipedia, the free encyclopedia

how do you convert acid halide to secondary alcohal by reaction with Grignard reagent??

That can't be done as you describe it. When a Grignard reacts with an acyl halide, a ketone is formed. Usually, a second molecule of the Grignard agent will then react with the carbonyl, giving a tertiary alcohol. If you could prevent this second reaction, you could reduce the ketone to a secondary alcohol, but doing so is hard for acyl halides and the reduction isn't a Grignard reaction. Or you could reduce the acyl halide to an aldehyde and then Grignard rxn would give secondary alcohol, but again, reduction ≠ Grignard. DMacks 05:55, 8 March 2006 (UTC)

[edit] Clean up

In think that in the hast to do the clean up that the article has been harmed by the removal of details of reactions with non-carbon electrophiles such as SnCl4. These are as much a part of Grignard chemistry as the reaction of the 'organic' carbon based electrophiles.Cadmium

So I did. Oops. I'll try to get to putting those back in either tonight or tomorrow. However, if you want to do it, go right ahead. ~K 15:42, 31 July 2006 (UTC)

You might also want to add NaBF4 + 4 RMgX to form Na BR4, this this the basics of how to make BPh4 anions.Cadmium

You beat me to it and did a much better job than I had planned. Thanks. ~K 17:23, 5 August 2006 (UTC)
