The weak sulfur-sulfur bond in elemental sulfur allows carbon-centred radicals and thiyl radicals to effect Sh2 reactions at such sulfur atoms leading to the formation of poly sulfides. For example [1], $$ Me_2 \dot CCN + S_8 \to Me_2 (CN)CS_n C(CN)Me_2 $$ and [2] $$ MeSSMe\xrightarrow{{120^\circ C}}2MeS \cdot $$ $$ MeS \cdot + S_8 ...

Organometallic Sulfur Compounds
1984Abstract The organometallic chemistry of S 2- and SH - ligands is outlined. The ability of substituent free sulfur to act as a two, four, or six electron donor and of the SH unit to act as a one, three, or five electron donor is the reason for structural diversity and the preference for polynuclear complexes.

Sulfur, in its various forms, is important to the yeast in protein biosynthesis as well as vitamins and coenzymes. Formation of volatile sulfur compounds plays an important role in sensory properties of wines. These compounds may be variously described as rubbery, onion, garlic, cabbage, kerosene-like, and skunky.

Organogallium-Sulfur Compounds
1986All compounds with Ga-S a bonds are listed in Table 48. They are mainly thiolates, GaR2SR’, most of them only recently prepared [12, 13]. The other derivatives contain potentially chelating ligands (Nos. 7 to 12 and No. 22), including chelating S N systems where it is impossible to distinguish between covalent and coordinative bonds to either the S or ...

The immense number of carbon-sulfur compounds in use today, both in medicine and agriculture, means that any review of the area can be best served only by the use of examples to highlight the general trends that exist in the various groups that comprise the collection of compounds that are classified as carbon-sulfur compounds.
