In connection with other investigations, we had need of 1, bdifunctionalized naphthalene derivatives such as carboxylic acids 4 and 6a. Because these compounds and derivatives thereof were unavailable commercially, our attention turned to synthetic approaches. We felt that 195-diiodonaphthalene (2)'would be ideally suited for our purposes, since it was potentially a precursor both of organometallic reagents and of compounds derived from ...
