Bourissou's group - LBPB

Yesterday, we held a farewell party for Sergio and Juan Carlos, who spent three months with us on the Gold Chemistry project. We hope the Toulouse gifts will be useful during the winter! See you guys!

Chimie organométallique : Didier Bourissou reçoit le prix Schlenk Didier Bourissou, directeur de recherche CNRS au Laboratoire hétérochimie fondamentale et appliquée, a obtenu le prix Schlenk, remis par l’université allemand

Congratulations to Didier Bourissou for the Schlenk price from Tübingen university and BASF: www.inc.cnrs.fr/fr/cnrsinfo/...

Very honored to be awarded the Schlenk lectureship. Much grateful to Univ. Tübingen & BASF for the support. Warmest thanks to Reiner Anwander & the whole team for taking care of me so kindly. It has been a wonderful time and I very much enjoyed meeting the members of the Schlenk family !

We are very pleased to annonced a new comer in our group as postdoctoral fellow, Dr Anna-lena THÖMMES @althoemmes.bsky.social for a 1.5 year contract. Coming from Pr David Scheschkewitz, she will work with us on Gold(0) chemistry. Good luck Anna-Lena for this news adventure with us!

Intramolecular Phosphinyl‐Zincation of Alkynes: A Powerful Entry to Benzophosphole Oxides Ortho-alkynylated secondary arylphosphine oxides undergo phosphinyl-zincation upon reaction with Et2Zn under gentle heating. The ensuing C3-zincated benzophosphole oxides have been characterized by m...

Benzophospholes are important molecules applied in optoelectronic. Our new paper in @angewandtechemie.bsky.social presents an original and versatile strategy to access BPOS via an intramolecular phosphinyl-zincation: onlinelibrary.wiley.com/doi/10.1002/... Enjoy the reading!

After spending 1.5 years as a postdoc in the group, Arindom is setting off on new adventures! Good luck Mr AB! We will miss your smile!!

Today we celebrated the end of Francesco's internship! It was a pleasure to have you in the group. We will miss you a lot not just for the pasta parties!!

Closer Look at the Substituent Effects on the Copolymerization of Thionolactones by Radical Ring-Opening Polymerization The negative impact of plastic waste on the environment is a serious issue for the future. Adding cleavable bonds to the polymer backbone can help to impart degradability properties. To this end, radical ring-opening polymerization (rROP) offers a very attractive way to achieve radical copolymerization with vinyl monomers. Thionolactones, one of the various cyclic monomers that can be used in rROP, are promising structures due to the efficiency of the C═S bond in acting as a radical acceptor. In this work, we used DFT calculations to better understand the effects of different substituents on the radical reactivity of thionolactones (dibenzo[c,e]oxepane-5-thione DOT derivatives) already described as more or less effective for copolymerization with vinyl monomers in order to adjust the reactivity of these thionolactones. To carry out these calculations, we focused on the value of the transfer constant ktr and its relationship to the propagation constant kp of the vinyl monomer. The calculations performed subsequently on 7-phenyloxepane-2-thione (POT) derivatives highlighted that electron-donating groups inserted in the para-position on the phenyl ring should improve the copolymerization efficiency with acrylate derivatives, and in contrast, electron-withdrawing groups should lead to more important compositional drift during styrene and acrylate copolymerization. Although POT derivatives bearing electro-donating groups could not be prepared, the preparation of those with CF3 and NO2 groups was successfully achieved. Experimental copolymerization of these two thionolactones with styrene and isobornyl acrylate is in good agreement with the calculations. This result confirmed the versatility and relevance of our calculation approach to account for the reactivity of thionolactones.

How a simple monomer can impact a material! Our last study on thionolactone as comonomer for radical ROP with Y Guillaneuf from ICR Marseille is out in Macromolecules. @pubs.acs.org pubs.acs.org/doi/abs/10.1...

Insertion of Nitriles Into a Gold(III)/Carbene Bond: A Direct and Powerful Entry to Imino‐Substituted Carbenes Stable imino-substituted Au(III) carbenes are easily and efficiently prepared by trapping the transient (N^C^C)Au←:CH(dmp)+ carbene with nitriles. The corresponding free species are readily generated...

Our lastest publication on stable imino-substituted Au(III) carbenes is available on @angewandtechemie.bsky.social !! Congratulations to Rui and Nina for this beautiful article.

Our great postdoc Dr Rui Wei left the group on monday after 2 years of productive collaboration on Gold chemistry! Thanks a lot Rui for this journey with the LBPB group! We already miss you so much! All the best for the rest of your career!!

After 3 productive years, Liyao Ma passed her PhD defense last friday with Prof @cbour.bsky.social and Prof Muriel Durandetti as referee and Prof Odile Dechy as president! You did a great job Liyao, we are very proud of you! Let’s wrap up the last results before you leave the group!

Congratulations to our new doctor, Arnaud Le Gac! You have perfectly concluded these 4 years in the group on PB chemistry with a disactic and clear presentation! Anew doctor of the LBPB is born!

Yesterday was the LHFA's annual safety meeting! Safety is very important in chemistry and everyone has a role to play! Never forget: Safety first!

Wittig reaction is not only a famous textbook reaction it’s also a colour production!! Check out this beautiful red-orange colour!

Happy birthday to our supramolecular guy, Youssoupha 🎉🥳🎂🎊! Croissant or chocolatine, what a difficult choice!!!

Today the group organized a pasta party! Many thanks to Gyorgy, Francesco, Liyao and Ghenwa for their delicious attention!
