Hi,
Im doing grignard reaction.. My compound is not getting dissolved in Diethyl ether. and as we dont have THF i have no choice.. My compound is an
ester(solid).. im very sure that the reagent is formed. but after adding my compound the reaction is not going. I couldnt figure out the reason.
I did the same reaction with benzyl bromide, it was positive. But with 1 bromo hexane is never goes for me. Could you guys plz help me with this???

Could you be more specific (reaction conditions, substrate, etc.)?
Are you trying to react hexylmagnesium bromide with an ester?
Is the problem that the substrate is insoluble in ether?

Yes. I tried with 1-Bromo hexane, and the ester which im trying with is not getting dissolved in ether. and actually Mr. cheese when i tried grignard
with the same ester using Bromo benzene, I got product.
I couldnt identify the problem, Im just guessing that the dissolution of My ester in ether might be the problem as I could see the generation of the
grignard reagent (complete dissolution of Mg turning, and dirty colour liquid).
Im doing the reaction under Nitrogen atmosphere. Im using a condenser, a connecter (where one opening to the nitrogen cylinder, one to the condenser
and one to a balloon filled with nitrogen).
Thank you so much
