Two catalytic systems for the formate-mediated cross-electrophile reductive coupling of 4-iodoansiole with 6-bromopyridines are described. Using homogenous rhodium or heterogeneous palladium catalysts, the product of reductive biaryl cross-coupling c

Iridium complexes modified by PhanePhos catalyze the 2-propanol-mediated reductive coupling of diverse 1,1-disubstituted allenes 1a-1u with fluoral hydrate 2a to form CF(3)-substituted secondary alcohols 3a-3u that incorporate acyclic quaternary carb

The air- and water-stable π-allyliridium C,O-benzoate modified by ( S)-tol-BINAP, ( S)-Ir-II, catalyzes highly regio- and enantioselective Tsuji-Trost-type aminations of racemic branched alkyl-substituted allylic acetates using primary or secondary

Alcohol-mediated carbonyl addition has enabled catalytic enantioselective syntheses of diverse fluorine-containing compounds without the need for stoichiometric metals or discrete redox manipulations. Reactions of this type may be separated into two

Stereo- and site-selective methods for the byproduct-free modification of unprotected organic compounds that occur through the addition or redistribution of hydrogen are natural endpoints in the advancement of methods for efficient chemical synthesis

The first catalytic enantioselective carbonyl (α-amino)allylations are described. Phthalimido-allene 1 and primary alcohols 2a–2z, 2a′–2c′ engage in hydrogen auto-transfer-mediated carbonyl reductive coupling by way of (α-amino)allyliridium

Metal-catalyzed reductive coupling has emerged as an alternative to the use of stoichiometric organometallic reagents in an increasingly diverse range of carbonyl and imine additions. In this monograph, the use of diene, allene and enyne pronucleophi

Using an iridium catalyst modified by PhanePhos, CF3-allenes react with methanol to form branched products of hydrohydroxymethylation as single regioisomers with excellent levels of enantiomeric enrichment. This hydrogen auto-transfer process enables
