Abstract:
A method for synthesizing a tin finctionalized alkali metal, comprising the steps ofa. reacting an organometallic compound having the formulaRR'R""Sn-M (I)wherein R, R' and R"" may be the same or different and each is a member independently selected from the group consisting of alkyl, aryl, aralkyl, and alkylaryl having from 1 to 15 carbon atoms and wherein each carbon atom may be unsubstituted or substituted, and M is an alkali metal selected form the group consisting of Li, Na or K, with a compound having the formulaXGX' (II)wherein X and X' may be the same or different and each comprises a halogen, and G is a substituted or unsubstituted branched, cyclic or straight chain hydrocarbon having from 1 to 20 carbon atoms, wherein the substitution is at least one aryl group, forming thereby a compound (Ill)RR'R""SnGX' (III)andb. reacting compound (III) with an alkali metal comprising Li, Na or K to form the tin functionalized alkali metal of formula (IV)RR'R""SnGM' (IV)wherein M' is Li, Na or K.
