Thiones, 60–65 kcal/mole, which is comparable to that of carbon-sulfur bonding. This indicates that the resonance energy in a thiocarbonyl group is great enough to compensate for the unfavorable energies of .–.-overlapping. Note that no carbon-silicon double bond has been found yet in stable compounds.

Vulcanization of Rubber, 130 years ago and the process has since become the basis of a world-wide commercial manufacturing industry, a scientific understanding of the changes taking place has begun to emerge only in the last 30 years. Many alternative reagents for effecting vulcanization have been discovered since 1840 but

Thiols,heir stink is as sensitive an analytical tool as tlc. Probably because of this reason, not much research has been done on the chemistry of thiols. Nevertheless thiols play very important roles for organisms and it is no exaggeration to say that no organism can maintain its life without thiols.

Disulfides and Polysulfides,or connected in a ring. Chapter 7 considers only substances where the S-R bond involves a carbon linkage; a review is available of structures such as ROS.OR and R.NS.NR.) Disulfides (n = 1) and their oxidation products are by far the most important subclass, but trisulfides and higher sulfides have

Sulfonium Salts,fore have the general structure: ABCSX̄. This is the most general description of sulfonium salts; this chapter will deal with those sulfonium salts in which at least two of the bonds to sulfur are from carbon. In most instances the third bond to sulfur will also be from carbon, but mention will be m
