DOI: 10.1021/acs.accounts.1c00664
Abstract: Conspectusα-Diazocarbonyl compounds serve as nucleophiles, dipoles, carbene precursors, and rare electrophiles, enabling a vast array of organic transformations under the influence of metal catalysts. Among them, rearrangement processes are attractive and provide straightforward and efficient… read more here.

DOI: 10.1021/acs.orglett.1c03992
Abstract: A coupling of acrylic acids/benzoic acids with α-diazocarbonyl compounds has been realized by a combined catalytic system of rhodium catalyst and Zn(OAc)2 additive. The presence of Zn(OAc)2 obviously accelerates the C(sp2)-H activation and destructed the… read more here.

DOI: 10.1021/acs.orglett.7b02139
Abstract: A new Rh-catalyzed, three-component reaction for the oxytrifluoromethylthiolation of α-diazoketones was developed. The SCF3 functionality was introduced using a stable dibenzenesulfonimide reagent under mild conditions. Alcohols, acetals, and ethers were used as the alkoxy sources.… read more here.

DOI: 10.1021/acs.orglett.7b03912
Abstract: Dirhodium(II) catalyzed dinitrogen extrusion from diazocarbonyl compounds by 2,6-dichloropyridine-N-oxide forms ketocarbonyl compounds in near-quantitative yields. Reactions occur at room temperature, and the pyridine product does not coordinate with dirhodium(II) to inhibit catalysis. Anhydrous tricarbonyl compounds,… read more here.

DOI: 10.1021/acs.orglett.9b00340
Abstract: An unprecedented cascade reaction of benzoyl sulfoxonium ylides with α-diazocarbonyl compounds leading to the formation of highly functionalized naphthalenones containing a β-ketosulfoxonium ylide moiety is presented. Promisingly, the naphthalenone derivative thus obtained was found to… read more here.
