(Pivaloyloxymethyl)zinc chloride, obtained by an iodine-magnesium exchange and subsequent transmetalation, shows a much higher reactivity in Negishi cross-couplings than the corresponding zinc organometallic, prepared by direct zinc insertion. Furthermore, a substituted derivative of (pivaloyloxymethyl)zinc chloride is prepared starting from pivaloyloxymethyl sulfoxide using TMPZnCl·LiCl (TMP = 2,2,6,6-tetramethylpiperidyl), followed by a sulfoxide-magnesium exchange.
