Tin: Organometallic Chemistry

Abstract

Frankland produced the first organometallic tin compound, Et 2 SnI 2 , in 1849. Since that time a wide range of tin compounds containing SnC bonds have been prepared. This article will detail the synthesis and characterization of these compounds. This will include a description of tetraorganotin compounds, halides, pseudohalides, hydrides, tin‐tin bonded compounds, radicals, group 15, and group 16 derivatives. The industrial and environmental aspects of these compounds will also be discussed.

Monomeric Triorganotin(IV) Fluorides Containing a C,N-Chelating Ligand

“…Such elongation of these bonds is caused by intramolecular interaction of the amino donor group in the trans position to the fluorine atom. The average Sn−F and Sn−F‘ distance in polymeric fluorides is 2.15 Å …”

“…The structures of many triorganotin fluorides have been determined and found to be either oligo- or polymeric with “rod-like” or “zig-zag” F−Sn−F chains 2e and cyclohexyl 3 SnF 2f were found to be 2.1458(3), 2.051(10), and 2.303(10) Å, respectively.…”

“…The structures of many triorganotin fluorides have been determined and found to be either oligo- or polymeric with “rod-like” or “zig-zag” F−Sn−F chains 2e and cyclohexyl 3 SnF 2f were found to be 2.1458(3), 2.051(10), and 2.303(10) Å, respectively. These compounds have relatively high melting points and are rather insoluble in common organic solvents, which was reported many times as a limitation in studies of their structure and reactivity.…”

Stereochemical Aspects of Enantiopure and Racemic Organolithium Aggregates Li4Ar4 {Ar = C6H4[CH(Me)NMe2]‐2}

“…[1,2] Their relatively simple synthesis and high reactivity make organolithium compounds often more attractive reagents in organic synthesis than are the corresponding Grignard reagents. The most widely used organolithium compound, nBuLi, is currently applied to both laboratory-scale syntheses and large-scale industrial processes.…”

“…( Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004) donor groups, which can be either solvent molecules or inter-or intramolecularly coordinating substituents in the organic monoanion. [2,12] These inter-and intramolecular donor groups are known to affect the synthesis and reactivity of organolithium reagents.…”
