Redox mediators of hydrogen sulfide oxidation in reactions with cycloalkanes
Berberova,Shinkar',Smolyaninov,Pashchenko
, p. 295 - 298 (2016/01/12)
An indirect electrochemical method for thiolation of cycloalkanes C5-C7 has been suggested. The method is based on a new approach to activation of hydrogen sulfide by redox mediators.
NONCONVENTIONAL FRIEDEL-CRAFTS CHEMISTRY IV. ON THE REACTION OF 1,3-OXATHIOLAN-5-ONE-2-SPIRO-1'-CYCLOALKANES WITH FERROCENE IN THE PRESENCE OF AlCl3 CATALYLST
Ei-Zohry, Maher F.
, p. 305 - 310 (2007/10/02)
The reaction of ferrocene with 1-oxa-4-thiaspirononan-2-one (1) and /or 1-oxa-4-thiaspiro-decan-2-one (2) in the presence of aluminum chloride catalyst afforded the spiroferrocene derivatives 4, 6, 5 and 7, respectively.The mechanism of these reactions is discussed.Key words: Friedel-Crafts reactions; ferrocene chemistry.
NONCONVENTIONAL FRIEDEL-CRAFTS CHEMISTRY III. ON THE REGIOSPECIFIC SYNTHESIS OF SPIRO-4'-ONE DERIVATIVES
El-Zohry, Maher F.
, p. 311 - 320 (2007/10/02)
The rection of 1-oxa-4-thiaspirononan-2-one (4) and/or 1-oxa-4-thiaspirodecan-2-one (5) with arenes (6) under the catalytic action of aluminum chloride afforded in all cases spiro-4'-ones (7a - g and 8a - g), -acetic acid, (9a - g and 10a - g), cycloalkylthioacetic acids, (11 and 20) aryl cycloalkyl sulfides, (14 and 23) diarylsulfides (15), diaryl disulfides and dicycloalkyl disulfides (13 and 22).The mechanisms of these reactions are discussed.Key words: Spiroisothiochroman-4-ones; Friedel-Crafts reactions.
Iron catalysed insertion of sulfur into the non-activated C-H bond
Balavoine,Barton,Gref,Lellouche
, p. 1883 - 1894 (2007/10/02)
The reaction of various sulfur reagents (S8, H2S, Na2S, NaHS) with cyclohexane under Gif(III), GoAgg(II) and GoAgg(III) conditions affords the usual oxidation products in competition with cyclohexyl di- and poly-sulfide formation. Other cyclic hydrocarbons behave similarly. The sulfation reactions are considered to be biomimetic for the enzymes isopenicillin N synthase and biotin synthase.
