METHYLTRIOXORHENIUM CATALYZED OXIDATION OF SECONDARY AMINES TO NITRONES TV-BENZYLIDENE-... [Pg.107]

Oxidation of thiophene with Fenton-like reagents produces 2-hydroxythiophene of which the 2(570 One isomer is the most stable (Eq. 1) <96JCR(S)242>. In contrast, methyltrioxorhenium (Vn) catalyzed hydrogen peroxide oxidation of thiophene and its derivatives forms first the sulfoxide and ultimately the sulfone derivatives <96107211>. Anodic oxidation of aminated dibenzothiophene produces stable radical cation salts <96BSF597>. Reduction of dihalothiophene at carbon cathodes produces the first example of an electrochemical halogen dance reaction (Eq. 2) <96JOC8074>. [Pg.78]

Oxidation of Primary Amines. Goti and coworkers described a one-pot condensation/oxidation of primary amines and aldehydes (eq 46) using UHP as stoichiometric oxidant in the presence of methyltrioxorhenium as catalyst. This reaction leads to nitrones in a simple and regioselective manner. From a sustainability point of view, this one-pot synthesis is simple to perform, takes place under mild conditions, and releases water as the only byproduct. ... [Pg.421]
