@BSadows1 @KabiArup @stefano_crespi @UniWarszawski @Boron_Chemistry Nice work! Do you know why the C-I bond cleavage is selective in your case? The use of arylbenziodoxolones has been often limited due to low selectivity in cleavage of one of the two aryl-I bonds...

Last week at the 8th International Symposium on C–H Activation (ISCHA-8) in Nanjing.
It was a fantastic meeting with inspiring science, stimulating discussions and reconnecting with old friends & meeting new faces.
Delighted to receive a talk award sponsored by @ACSPublications

We are looking for candidates for a PhD position in my group (https://t.co/qGOKcvdXtK) at @UMU to work on new methods for sustainable organic synthesis based on iron photocatalysis.
Deadline: October 1st
More info about the position in the doc below 👇
RT are appreciated!

Check our latest work in @J_A_C_S! We disclose a stereoretentive Yang photocyclization, enabling efficient synthesis of highly substituted cyclobutanols whilst preserving stereochemical information encoded in substrates derived from the chiral pool. https://t.co/LpOcRLzcoE

[Sc•EYE•ce @Benjamin__Large]

Just finished a cover to illustrate this paper from @LcsoLab on bicyclobutane transfer reagents!
A smart strategy for making strained BCB scaffolds and accessing sulfur-and carbon-substituted products!
Check it out on @ChemRxiv!
