Thiols from alcohols. In toluene or DME the Lawesson s reagent directly converts aralkyl and cycloalkyl alcohols to thiols. [Pg.51]

Halogenation and nitration of arenes, substitution reactions ofaliphatics Ether and ester formation, thiols from alcohols and H2S, amines from alcohols and NHj (mordenite, erionite)... [Pg.257]

Dissolved in 20% NaOH, extracted with a small amount of C6H6, then steam distd, until clear. The soln was then cooled and acidified slightly with 15% H2SO4. The thiol was distd out, dried with CaS04 or CaCl2, and fractionally distd under N2 [Mathias and Filho J Phys Chem 62 1427 1958]. Also purified by pptn as lead mercaptide from alcoholic soln, with regeneration by adding dilute HCl to the residue after steam distn. All operations should be carried out in a fume cupboard due to the TOXICITY and obnoxious odour of the thiol. [Pg.143]

Double nucleophilic substitution can similarly be achieved by alkoxides of sufides generated in situ from alcohols of thiols in the presence of K2C03 [99] Eq. (29) and Table 9. [Pg.78]

Thiols have also been prepared from alcohols. One method involves treatment with H2S and a catalyst such as A1203, but this is limited to primary alcohols. [Pg.496]

The hydroxy groups in natural products like, for example, the macrolide antibiotics erythromycin, 1"1 and desmycosin, 2001 2011 as well as the 3-(hydroxymethyl)-2- or 3-cephems 2021 and derivatives of the amino sugar garamin 2031 have been converted into the carbamate function with CDI and amines. In the case of aminoglycoside antibiotics of the sisomicin series, thiocarbamates or dithiocarbamates have been prepared from alcohols or thiols using ImCSIm and amines.12041... [Pg.142]
