Facile 1,1-carboboration reactions of acetylenic thioethers
Eller, Christina,Kehr, Gerald,Daniliuc, Constantin G.,Froehlich, Roland,Erker, Gerhard
, p. 384 - 386 (2013/03/14)
The acetylenic thioether PhSCi - CSPh undergoes a rapid 1,1-carboboration reaction with facile -SPh migration upon treatment with B(C6F5)3 to yield the borylated ketene dithioacetal product (PhS)2C=C(C6/su
Solvolytically DMSO-promoted reactions of 1,1,1-trifluoroethyl chloride (HCFC-133a) or fluoride (HFC-134a) with nucleophiles

Fluorinated gases HCFC-133a (CF3CH2Cl, bp=6°C) and HFC-134a (CF3CH2F, bp=-27°C) are found highly soluble in DMSO. In their DMSO solutions, oxygen-, nitrogen- and sulfur-nucleophilic reactions may occur in normal
A New Approach to the Synthesis of Symmetrical Bis(organylchalcogeno)acetylenes: Scope and Limitations

A new general method to prepare bis(organylchalcogeno)acetylenes R-Y-CC-Y-R (Y = S, Se, Te) by dehydrochlorination of the corresponding 1,2-bis(organylchalcogeno)chloroethylenes R-Y-CH=CCl-Y-R with tert-BuOK/tert-BuOH and/or KOH/DMSO is developed.Dechlorination of 1,2-bis(organylchalcogeno)-1,2-dichloroethylenes R-Y-CCl=CCl-Y-R (Y = S, Se, Te) with BuLi in ether or THF is effective only for sulfur derivatives.With Y = Se and alkyl substituents, substitution of the chlorine atom by a butyl group takes place giving rise to 5,6-bis(alkylseleno)dec-5-ene .With aryl substituents, an attack of the ArSe-group by the Bu-radical is observed leading to an aryl butyl selenide.In the case of the tellurium compound Ph-Te-CCl=CCl-Te-Ph, there is a competition between dechlorination to give Ph-Te-CC-Te-Ph, and substitution to produce the phenyl butyl telluride. - Keywords: bis(organylchalcogeno)acetylene; 1,2-bis(organylchalcogeno)chloroethylene; 1,2-bis(organochalcogeno)-1,2-dichloroethylene.
Preparation and Chemistry of PhI+C≡CI+Ph·2-OTf, Bis[phenyl[[(trifluoromethyl)sulfonyl]oxy]iodo]acetylene, a Novel Difunctional Acetylene, Bis(iodonium) Species and a Stable C2-Transfer Agent

The title compound 2 is readily prepared as a stable microcrystalline solid from bis(tri-/i-butylstannyl)acetylene and PhICN-OTf. It was fully characterized by multinuclear NMR, IR, and elemental analysis. As expected, the electron-deficient acetylene 2 r
Reactions of 2,2-Dichlorovinyl and 2,2-Dichlorovinylidene Sulfides with Butyllithium

The present paper describes the reactions of two series of compounds, RS(R'S)C=CCl2 and RS(R')C=CCl2, with butyllithium.The former gives 1,2-dithio-substituted acetylenes by rearrangement, whereas the latter gives cumulenes by dimerization. Keywords --- 2
