The borrowing hydrogen (BH) principle, also called hydrogen auto-transfer, is a powerful
approach which combines transfer hydrogenation (avoiding the direct use of molecular …

The selective and efficient C–H methylation of sp2 and sp3 carbon centres has become a
powerful transformation in the synthetic toolbox. Due to the potential for profound changes to …

Homogeneous catalysis of organic transformations by metal complexes has been mostly
based on complexes of noble metals. In recent years, tremendous progress has been made …

Transition‐metal‐catalyzed C‐alkylation of ketones and secondary alcohols, with alcohols,
avoids use of organometallic or environmentally unfriendly alkylating agents by means of …

A general iron-catalyzed methylation has been developed using methanol as a C1 building
block. This borrowing hydrogen approach employs a Knölker-type (cyclopentadienone) …

The development of catalytic reactions for synthesizing different compounds from alcohols to
save fossil carbon feedstock and reduce CO2 emissions is of high importance. Replacing …

Being the third most abundant transition metal in the Earth's crust (after iron and titanium)
and less toxic, reactions catalyzed by manganese are becoming very important. A large …

The combination of nickel metallaphotoredox catalysis, hydrogen atom transfer catalysis,
and a Lewis acid activation mode, has led to the development of an arylation method for the …

Since alcohols are accessible from indigestible biomass (lignocellulose), the development
of novel preferentially catalytic reactions in which alcohols are converted into important …

The nickel‐catalyzed three‐component reductive carbonylation of alkyl halides, aryl halides,
and ethyl chloroformate is described. Ethyl chloroformate is utilized as a safe and readily …
