An unusual case of bis-methoxymercuration of diphenylethyne. Molecular structure of PhC(HgCl)2C(OMe)2Ph
Abstract
Addition of aqueous KCl to the reaction of diphenylethyne and mercury(II) acetate in methanol induces an unprecedented geminal double mercuration of the triple bond; the X-ray crystal structure of the product shows an unusually short Hg(1)–Hg(2) interatomic distance.
