Abstract:
The synthesis of a terphenyl-substituted lithium dithiosilacarboxylate dimer via the reaction of the corresponding aryltrifluorosilane with lithium (trimethylsilyl)thiolate is presented. Its molecular structure was determined by single-crystal X-ray diffraction analysis, which revealed a cis-geometry for the Si2S2 core in the crystalline state. Treatment of this complex with an excess of methyl iodide afforded the corresponding methyl ester dimer. Spectroscopic analyses suggested that neither the lithium dithiosilacarboxylate dimer nor the methyl dithiosilacarboxylate dimer dissociate homolytically in solution, not even at high temperatures.

01:15Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.

01:28Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the...
