L’école de cristallographie de Nancy : un hommage

The recent death of Professor Yves Dusausoy, one of my first crystallography teachers, gave me the desire to write a article in tribute to the “Nancy school”, where I had the chance to do my scientific studies before embarking on my own career as assistant professor (1994–2000, Henri Poincaré University) and then full professor at Strasbourg University from 2000. They are specifically three “great” deceased teachers who marked my scientific formation and allowed me to be well prepared in the large field of X-ray crystallography.In this article, I want to pay tribute to the Professors Yves Dusausoy, Jean Protas and Niels Hansen and show, on a few easy examples, the relevance of their respective teachings

Photocatalytic Aminodecarboxylation of Carboxylic Acids

Aminodecarboxylation of unactivated alkyl carboxylic acids has been accomplished utilizing an organic photocatalyst. This operationally simple reaction utilizes readily available carboxylic acids to chemoselectively generate reactive alkyl intermediates that are not accessible via conventional two-electron pathways. The organic radical intermediates are efficiently trapped with electrophilic diazo compounds to provide aminated alkanes.Division of Chemistry. Grant Number: 146517

(3-Anilino-1-phenyl­imino­thio­ureato)chloridodimethyl­tin(IV)

In the title compound, [Sn(CH3)2(C13H11N4S)Cl], the Sn atom is five-coordinated in a distorted trigonal-bipyramidal geometry, with two methyl groups and one S atom in the equatorial plane, and one N atom and the Cl atom occupying the apical positions

N,N′-Dibenzyl-N′′-(4-bromo­benzo­yl)-N,N′-dimethyl­phospho­ric triamide

In the title compound, C23H25BrN3O2P, the P atom has a distorted tetra­hedral coordination. In the crystal structure, the mol­ecules form centrosymmetric dimers via pairs of essentially linear N—H⋯O hydrogen bonds
