Oxidant-free Au-catalyzed reactions are emerging as a new synthetic tool for innovative organic transformations. Still, a deeper mechanistic understanding is needed for a rational design of these processes. Here we describe the synthesis of two Au(I) complexes bearing bidentated hemilabile MICˆN ligands, [AuI(MICˆN)Cl], and their ability to stabilize square-planar Au(III) species (MIC = mesoionic carbene).

Eumelanin is the biopolymer responsible for photoprotection in living beings and holds great promise as a smart biomaterial, but its detailed structure has not been characterized experimentally. Theoretical models are urgently needed to improve our knowledge of eumelanin’s function and exploit its properties, but the enormous amount of possible oligomer components has made modelling not
New-to-nature radical biocatalysis has recently emerged as a powerful strategy to tame fleeting open-shell intermediates for stereoselective transformations. In 2021, it was introduced a novel metalloredox biocatalysis strategy that leverages the innate redox properties of the heme cofactor of P450 enzymes, furnishing new-to-nature atom-transfer radical cyclases (ATRCases) with excellent activity and stereoselectivity. Herein, it is

A large number of 2D/2D and 3D/3D aromatic fusions that keep their aromaticity in the fused compounds have been synthesized. In addition, we have previously proven the electronic relationship between the 3D aromaticity of boron hydrides and the 2D aromaticity of PAHs. Here we report the possible existence of 3D/2D aromatic fusions that retain the
Dr. Galeotti has recently become a new member of the Institute of Computational Chemistry and Catalysis (IQCC) as a postdoc. Dr. Galeotti received his PhD in Chemistry from University of Rome “Tor Vergata” (Italy) in 2022. During his PhD, he worked with Prof. Massimo Bietti and Prof. Michela Salamone on factors governing reactivity and selectivity
This week at the XXXVIII Bienal RSEQ conference in Granada, three IQCC PhD students won awards for the best poster in different symposia. • Ernest Ubasart, PhD student under the supervision of Dr. Xavi Ribas, presented his work on Large Tetragonal Prismatic Supramolecular Nanocapsules as Multi-Functional Platforms, and won one of the best poster awards in
