Abstract
The reaction of a quaternary ammonium salt of the tin chloride-substituted polyoxometalate, [PSn(Cl)W(11)O(39)](4-), with a variety of n-nucleophiles including primary, secondary, and tertiary amines and a tertiary phosphine, yielded tin-centered Lewis acid-base adducts, [PSn(Cl)W(11)O(39)](4-)-n-nucleophile; with more nucleophilic secondary amines such as diisopropylamine, apparently some [PSnN[CH(CH(3))(2)](2)W(11)O(39)](4-) was formed as a minor product. The compounds were identified by (1)H, (119)Sn, (15)N, (31)P, and (183)W NMR, ESI-MS, and elemental analyses. The key connectivity of the Sn-Cl center with the amine was clarified by the observation of (3)J Sn-H couplings (Sn from the polyoxometalate cluster and H from the amine moiety) in a 2D (119)Sn-(1)H heteronuclear multiple-bond correlation NMR experiment. This new, rather simple synthetic method was also utilized for preparing amino acid-polyoxometalate hybrid compounds.
