Recent Advances in Enantioselective Photochemical Reactions of Stabilized Diazo Compounds [PDF]

open access: yesMolecules, 2019
Diazo compounds have proven to be a useful class of carbenes or metal carbenoids sources under thermal, photochemical, or metal-catalyzed conditions, which can subsequently undergo a wide range of synthetically important transformations.

Electrochemical oxidative difunctionalization of diazo compounds with two different nucleophiles [PDF]

open access: yesNature Communications, 2023
The difunctionalization of diazo compounds, traditionally with one nucleophile and one electrophile, is a powerful strategy. Here, the authors develop a path of electrochemical oxidative difunctionalization of diazo compounds with two different ...

[2 + 1] Cycloaddition reactions of fullerene C60 based on diazo compounds [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2021
The most common variant of fullerene core functionalization is the [2 + 1] cycloaddition process. Of these, reactions leading to methanofullerenes are the most promising. They are synthesized in two main reactions: nucleophilic cyclopropanation according

Rh(III)-Catalyzed Annulation of Boc-Protected Benzamides with Diazo Compounds: Approach to Isocoumarins [PDF]

open access: yesMolecules, 2019
A mild rhodium-catalyzed annulation of Boc-protected benzamides with diazo compounds via C−C/C−O bond formation has been explored. In the presence of [Cp*RhCl2]2, AgSbF6 and Cs2CO3, Boc-protected benzamides can be effectively annulated to ...
