thanks for the help, just pulled up that paper.
by the way I did some reading and i found pic related. apparently with larger cuprate moieties, the solubility of the lithium iodocuprates increases (vs dimethyl cuprates which precipitate)
J. Am. Chem. Soc. 2014, 136, 5765?5772
i think i will either go through the Grignard route or maybe try the cyanocopper route
