Excited to share some work on how iridium diphosphine complexes with a Lewis acidic secondary coordination sphere influences selective heteroarene borylation! @marcuswdrover @ChemUWindsor @UWindsor #RSCPoster #RSCInorg

@Callum_Woof @marcuswdrover @jzurakowski1 @AustenBrady @ChemUWindsor @UWindsor Hi Callum, thank you so much! We believe the intermediate complexes in square brackets have a short lifetime due to their reactivity and are too fast to be observed in situ. We also performed EPR and did not observe any non-spin = 0 compounds!

@Chemrissa @marcuswdrover @jzurakowski1 @AustenBrady @ChemUWindsor @UWindsor Hi Marissa! Yes you are correct, ligand dissociation is required for PhI to perform oxidative addition! We did attempt to synthesize the single phosphine ligand Ni(COD) complex, however we found only the bis(P2BCy4) Ni complex can be obtained.

@DemchukMitchell @marcuswdrover @jzurakowski1 @AustenBrady @ChemUWindsor @UWindsor Looks like ligand dissociation to get oxidative addition of PhI is a key step for this work. The ligand also looks hard to make.. do you think you could get similar results using a single phosphine ligand Ni COD complex so you are loosing an equivalent of COD vs. borylated ligand
