Nitroxides, also known as nitroxyl radicals, are long-lived or stable radicals with the general
structure R1R2N–O•. The spin distribution over the nitroxide N and O atoms contributes to …

Advances in the field of transition-metal-free nitroxide-catalyzed aerobic oxidation processes
are covered in this critical review. Along with the relevant physical properties of nitroxides …

The organic nitroxyl radical, TEMPO (2, 2, 6, 6-tetramethylpiperidine-N-oxyl), finds a variety
of industrial applications for chemical transformations. Because of economic and …

The present review summarizes primary publications on the cross-dehydrogenative C–O
coupling, with special emphasis on the studies published after 2000. The starting …

A unique lipase (SpL) from Sphingomonas sp. HXN-200 was discovered as the first
intracellular enzyme for the aminolysis of ester or acid to produce amide. Reactions of a …

A method has been developed for the direct conversion of aldehydes to thioesters via
integration of organocatalysis and electrosynthesis. The thiazolium precatalyst was found to …

Oxoammonium salt oxidations (using 4-acetylamino-2, 2, 6, 6-tetramethylpiperidine-1-
oxoammonium tetrafluoroborate) of alcohols containing a β-oxygen atom in the presence of …

The cerium-doped Y-type barium hexaferrites Ba 2− x Ce x Co 2 Fe 12 O 22 (x= 0.0, 0.1, 0.2,
and 0.3) were synthesized using the sol–gel auto combustion method. The synthesized …

Identifying the mechanism of a catalytic reaction is paramount for designing new and
improved catalysts. Several alternative catalytic cycles for the copper/2, 2, 6, 6 …

A readily prepared C2-symmetric, α-hydrogen-substituted chiral hydroxylamine serves as a
precatalyst to generate a chiral nitroxide in situ. This chiral nitroxide catalyst in combination …
