Allyl p-tolyl sulphoxide 535 reacts with sodium methoxide in methanol by initial prototropic isomerization and subsequent addition of methanol to give 536 (equation 333). Protic solvents are photochemically incorporated by the open chain olefinic bond of trans methyl )S-styryl sulphoxide 537 in a Markovnikov regiospecificity (equation 334). Mercaptanes and thiophenols add to vinyl sulphoxides in a similar manner (compare also Reference 604 and Section IV.B.3) to give fi-alkylthio(arylthio)ethyl sulphoxides 538 (equation 335). Addition of deuteriated thio-phenol (PhSD) to optically active p-tolyl vinyl sulphoxide is accompanied by a low asymmetric a-induction not exceeding 10% (equation 336) . Addition of amines to vinyl sulphoxides proceeds in the same way giving )S-aminoethyl sulphoxides in good to quantitative yields depending on the substituents at the vinyl moiety When optically active p-tolyl vinyl sulphoxides are used in this reaction, diastereoisomeric mixtures are always formed and asymmetric induction at the p- and a-carbon atoms is 80 20 (R = H, R = Me) and 1.8 1 (R = Me, R = H), respectively (equation 337) ... 

Thus, the transfer agents commonly used are mercaptans (for example tert-dodecylmercaptane [62]), enol-ethers [63], carbon tetrachloride [64], isopropyl alcohol [56, 65], triethyl amine [38], and diethylamine, ethyl benzene toluene [66]. Tert-dodecylmercaptane is a very efficient transfer agent but, even used at very low concentrations (0.1-0.3%), generates an unpleasant odour (characteristic of mercaptans) in the final polymer polyol. This is the reason why other transfer agents, without unpleasant odour but with a modest transfer efficiency, are preferred, such as isopropyl alcohol, which needs to be used in higher concentrations (4-8% against final polymer polyol) ... 

ETHYL MERCAPTAN (75-08-1) Forms explosive mixture with air (flash point <0°F/<-18°C). Reacts with water, steam acids, acid fumes, forming hydrogen sulfide. Violent reaction with strong oxidizers, calcium hypochlorite. Incompatible with aliphatic amines, caustics, ethylene oxide, isocyanates, nitric acid, sulfuric acid. Attacks some forms of plastics, coatings, and rubber. Flow or agitation of substance may generate electrostatic charges due to low conductivity. 

Saturated Aliphatic Compounds Containing Heteroatoms. A great variety of organic matter falls in this classification—for example, alcohols, ethers, mercaptans, amines, and halides. Two types of simple cleavage reactions may occur that are initiated or directed by the presence of the heteroatom (O, S, N, X, etc.), as exemplified by Equations 16.18 and 16.19 for ethyl ether. Heteroatoms that can stabilize the positive... 

Bisphenol A is produced by the condensation reaction of excess phenol with acetone in the presence of an acidic catalyst. Sulfur compounds that may be used as a cocatalyst include alkyl mercaptans, such as methyl mercaptan, ethyl mercaptan, and thioglycol acid. Recently, a catalyst composed of an acid-type ion exchange resin, which is modified in part with a sulfur-containing amine compound, has been disclosed [16]. Bisphenol A is used for a wide variety of resins, mostly in the production of epoxy resins.
