Abstract

A series of bis(diphenylbromostannyl)alkanes of the type (C6H5)2BrSn(CH2)nSnBr(C6H5)2, where n = 6, 10 and 12, and a series of bis(tributylstannyl)carboxylates of the type (n-C4H9)3SnO2C(CH2)nCO2Sn(n-C4H9)3, where n = 2, 6, 10, 12 and 14, were prepared. Tin-119 solid state NMR of the carboxylates indicated that the compounds contain five-coordinate, structurally-equivalent tins in the solid state. Adduct formation with triethylphosphine oxide (TEPO) for both the alkanes and carboxylates was monitored by phosphorus-31 NMR. Equilibrium constants for the alkanes were approximately independent of chain length from n = 6 to 12, while for the carboxylates, the constants for n = 2 and n = 14 were small. Equilibrium constants for the intermediate chains were approximately the same. Solid state NMR shows that the 1:1 TEPO adduct of the n = 12 carboxylate contains two different tin atoms, both of which are five-coordinate, and that the adduct is probably not symmetrically chelated.
