The marked influence of steric and electronic properties of ancillary pyridylthioether ligands on the rate of allene insertion into the palladium-carbon bond was written by Canovese, Luciano;Visentin, Fabiano;Chessa, Gavino;Santo, Claudio;Uguagliati, Paolo;Bandoli, Giuliano. And the article was included in Journal of Organometallic Chemistry in 2002.Application In Synthesis of Sodium 2-methyl-2-propanethiolate This article mentions the following:

Neutral Me chloro complexes (L)Pd(Me)Cl 1 containing 6-R’-2-R-thiomethylpyridine ancillary ligands L (R’N-SR, R’ = H, Me, Cl; R = Me, Et, CHMe₂, CMe₃, Ph) were obtained by reaction of L with (COD)Pd(Me)Cl. Complexes 1 were carbonylated with CO to give corresponding acetyl derivatives 2. Kinetics of insertion of 1,1-dimethylpropadiene and 1,1,3,3-tetramethylpropadiene into the palladium-carbon bond in 1 and 2 was studied by ¹H-NMR and UV-vis techniques. The rate of reaction is strongly dependent on the steric and electronic properties of the ancillary ligand and of the allene. The distortion induced by R’ on the main coordination plane of the complex (allowed by sulfur sp³ hybridization) activates the complex to nucleophilic attack by the allene. Increase of electrophilicity of the palladium core, caused by lowering of the basicity of L results in further enhancement of the rate of allene insertion. The rate constants for complexes with L = 6-chloro-2-phenylthiomethylpyridine (ClN-SPh) are the greatest observed so far for similar reactions. The associative asynchronous mechanism of the insertion reaction is discussed. In the experiment, the researchers used many compounds, for example, Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2Application In Synthesis of Sodium 2-methyl-2-propanethiolate).

Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Application In Synthesis of Sodium 2-methyl-2-propanethiolate

C-H and C-S Bond Cleavage in Uranium(III) Thiolato Complexes was written by Arliguie, Therese;Lescop, Christophe;Ventelon, Lionel;Leverd, Pascal C.;Thuery, Pierre;Nierlich, Martine;Ephritikhine, Michel. And the article was included in Organometallics in 2001.Electric Literature of C4H9NaS This article mentions the following:

Reduction of the uranium(IV) thiolates Cp^*₂U(SR)₂ (Cp^* = η-C₅Me₅, R = Ph, Me, ⁱPr or ^tBu) with sodium amalgam afforded the corresponding U(III) complexes Na[Cp^*₂U(SR)₂] (R = Ph, 2a; Me, 2b; ⁱPr, 2c) or the U(IV) sulfide Na[Cp^*₂U(S^tBu)(S)]. C-S bond cleavage of a thiolate ligand was also observed during the thermal decomposition of 2c into the sulfide Na[Cp^*₂U(SⁱPr)(S)], whereas 2b was transformed in refluxing THF into the thiametallacyclopropane complex Na[Cp^*₂U(SMe)(SCH₂)], resulting from C-H bond activation of a SMe group. The x-ray crystal structures of [Na(18-crown-6)(THF)₂][Cp^*₂U(SⁱPr)₂], [Na(18-crown-6)][Cp^*₂U(S^tBu)(S)], and [Na(18-crown-6)(THF)₂][Cp^*₂U(SMe)(SCH₂)] have been determined In the experiment, the researchers used many compounds, for example, Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2Electric Literature of C4H9NaS).

Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Electric Literature of C4H9NaS

Activation of H₂ and CO by sulfur-rich nickel model complexes for [NiFe] hydrogenases and CO dehydrogenases was written by Sellmann, Dieter;Prakash, Raju;Heinemann, Frank W.. And the article was included in European Journal of Inorganic Chemistry in 2004.Category: alcohols-buliding-blocks This article mentions the following:

Reactions of the trinuclear complexes [Ni(^RS₃)]₃ [^HS₃^2- = bis(2-mercaptophenyl)sulfide(2-) (1a) or ^siS₃^2- = bis(2-mercapto-3-trimethylsilylphenyl)sulfide(2-) (1b)] with nucleophiles L (L = NHPnPr₃, NHPCy₃, NHSPh₂, PnPr₃) afforded the corresponding mononuclear complexes [Ni(L)(^RS₃)] [R = si = SiMe₃; L = NHPnPr₃ (2b); L = NHPCy₃ (3a,b); L = NHSPh₂ (4a,b); L = PnPr₃ (5a)]. X-ray structural determinations showed that 2b, 3a, 3b, 4a, and 5a exhibit tetrahedrally distorted planar [Ni(L)(^RS₃)] fragments. Complex 2b dimerizes through intermol. N-H…N hydrogen bonding. In contrast to 2b, complexes 3a and 4a exhibit intramol. hydrogen bonds between thiol groups and NH protons. Complexes 2-4 possess weakly acidic NH protons and undergo D⁺/NH exchange reactions with D₂O or CD₃OD. Complexes 2-4 and [Ni(StBu)(^RS₃)]^– (9a,b) also catalyze D₂/H^– exchange in [D₈]THF/H₂O under an elevated pressure of D₂ (18 bar), as confirmed by ¹H NMR spectroscopy. It is proposed that D₂ heterolysis is achieved through attack of the Lewis-acidic nickel centers and the Broensted-basic sulfur atoms at an η²-D₂ ligand. Complexes 9a and 9b are the first sulfur-only nickel complexes that enable the modeling of the [NiFe] hydrogenase catalyzed D₂/H⁺ exchange reaction. Evidence for labile five-coordinate [Ni(CO)(L)(^RS₃)] has been found in the reaction between [Ni(L)(^RS₃)] complexes and CO. The CO adducts of complexes with nitrogenous ligands L such as N₃^–, NHPR₃ (R = nPr₃, Cy₃), or NHSPh₂ showed rapid consecutive reactions. The reaction between Et₄N[Ni(N₃)(^siS₃)] (8b) and CO gave Et₄N[Ni(NCO)(^siS₃)] (10b), whereas reactions between 2-4 and CO afforded only 1a or 1b. Mechanisms are suggested which have the formation of reactive five-coordinated [Ni(CO)(L)(^RS₃)] intermediates in common. In the experiment, the researchers used many compounds, for example, Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2Category: alcohols-buliding-blocks).

Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Category: alcohols-buliding-blocks
