A new practical one-pot access to sulfonimidates

(matrix presented) Sulfonimidates were prepared from sulfinamides and iodosobenzene in a very mild one-pot procedure in good to excellent yields. This reaction allows quick and efficient access to a class of molecules of important synthetic as well as biological and industrial interest.

Synthesis, crystal structure, optical, electrochemical and thermal properties of the ynamide: Bis-(N-4-methylbenzenesulfonyl, N-n-butyl)-1,3-butadiyne-1,4-diamide

The novel ynamide compound, bis-(N-4-methylbenzenesulfonyl, N-n-butyl)-1,3-butadiyne-1,4-diamide (3), was synthesized and characterized by single crystal X-ray diffraction, 1H and 13C NMR, UV-fluorescence spectroscopy, cyclic voltammetry, TGA and DSC techniques. This first reported X-ray structure of a 1,3-butadiyne-1,4-diamide revealed that the amido substituents of 3 adopt a twisted conformation in the crystal with a torsion angle of 76.6° resulting in a molecule with axial chirality. The crystal structure of compound 3 is stabilized by intermolecular CH-π interactions that give pairs of stacked bis-alkyne-3 units. HOMO/LUMO energy levels of 3 were experimentally determined by means of electrochemical and optical methods to be??5.87/?1.98?eV respectively. The solid state polymerization of the title compound was investigated by differential scanning calorimetry (DSC) revealing that polymerization proceeded simultaneously to the phase transition assigned to the melting of 3. The solid state polymerization of 3 is discussed of being a topochemically initiated polymer chain reaction that proceeds with a non-topochemical chain growth.

Direct conversion of sulfinamides to thiosulfonates without the use of additional redox agents under metal-free conditions

Direct conversion of sulfinamides to thiosulfonates is described. Without the use of additional redox agents, the reaction proceeds smoothly in the presence of TFA under metal-free conditions. This protocol possesses many advantages such as odourless and stable starting materials, broad substrate scope, selective synthesis, and mild reaction conditions. This journal is

Catalyst-free one-pot, four-component approach for the synthesis of di- And tri-substituted: N -sulfonyl formamidines

A straightforward one-pot, multicomponent approach was developed to synthesize di- and tri-substituted N-sulfonyl formamidines from sulfonyl chlorides, NaN3, ethyl propiolate, and primary/secondary amines under mild conditions without catalysts or additives. Structural analysis of the di-substituted sulfonyl formamidines indicated formation of the E-syn/anti isomeric form. Tri-substituted analogues only formed E-isomers.
