I have a paper where they produce it in situ from 4-bromoanisole and some silver sodium alloys. Anything silver is expensive and the procedure itself is a little complex. I am not against making it, but I figure why not buy already made from a supplier.
The thing is, it isnt sold on sigma. Is there a reason? I know it is reactive but so is t-butyl lithium.
Any thoughts on why it may not be available commercially?
