The preparation of alkylidene sulfur tetrafluorides, R 2C SF 4, is presented. They exhibit a rigid structure, which can be described as trigonal bipyramidal or pseudo-octahedral around sulfur. The chemistry is mostly addition across the sulfur carbon double bond, but also carbene formation. In ...
The sulfur–sulfur bond dissociation enthalpies in 12 disulfide compounds were calculated using high-level ab initio methods including G3, G3B3, CBS-Q, CBS-4M, CCSD(T), and ROMP2. The theoretical bond dissociation enthalpies calculated by different methods generally agreed well with each other...

Reaction of sulfur with Ga-C bonds: Synthesis and...Reports on the reactions of Ga(CH2CH3)3 with variable quantity of elemental sulfur S8, in toluene or benzene at various temperatures. How the sulfur insertion reaction pathway was examined; Description of one method to prepare metal-sulfur ...
With the aid ofX-ray crystallography, they discovered that the enzyme not only binds several of these molecules to its active site but also modifies them: Through the additionof water to the acetylene groups (hydrocarbons with triple bonds), the compounds are converted to aldehydes or ketones. ...
Its density is 1.96 g/cm3, with a melting point of 119.3°C.3. Amorphous sulfur is formed when molten sulfur is quickly cooled. Amorphous sulfur issoft and elastic, and as it cools, it reverts back to the orthorhombic allotropic form.Sulfur, in its elemental form, is rather common and ...
