Abstract

Abstract Lithiated 1, 3-dithianes react with trialkyltin or triphenyltin chlorides to form the corresponding 1, 3-dithian-2-yltin compounds. The dithiane C (2) Sn bond in the trialkyltin or triphenyltin compounds is selectively cleaved by iodine, with formation of 1, 3-dithian-2- ylium triiodides which can be transformed into the corresponding tetrafluoroborate salts. The 1 H and 13 C NMR data are consistent with the salt like structures. The ambident nature of ...
