Merging hydrogen (H2) evolution with oxidative organic synthesis in a semiconductor-
mediated photoredox reaction is extremely attractive because the clean H2 fuel and high …

Following a strong regain of interest over the past 20 years in the chemistry of allenes, this
“forgotten” family of unsaturated molecules is undergoing a renaissance. In this context, the …

Semiconductor-based photoredox catalysis brings an innovative strategy for sustainable
organic transformation (eg, C–C/C–X bond formation), via radical coupling under mild …

The sun offers a clean and renewable energy cornucopia, whereas how to utilize this
inexhaustible yet decentralized energy with the assistance of appropriate media is an …

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 …

Metal-catalyzed reductive coupling has emerged as an alternative to the use of
stoichiometric organometallic reagents in an increasingly diverse range of carbonyl and …

Hydrofunctionalisation and difunctionalisation of dienes, allenes, and alkynes are widely
utilized in the synthesis of valuable allylic compounds. In the past decades, asymmetric …

Transition metal-catalyzed substitution of alcohols by N-nucleophiles (or N-alkylation of
amines and related compounds with alcohols) avoids the use of alkylating agents by means …

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

BACKGROUND Since the discovery of the Grignard reaction more than a century ago,
carbonyl addition mediated by premetalated reagents has played a central role in synthetic …
