Professor of Chemistry (Dalhousie Univ., 🇨🇦), dad, husband, semi-capable rock drummer. Politically ranty. Chemgeekery. Opinions my own. He/him.
Our collaboration w/ @markstradiotto.bsky.social and team is now out in Chem. Eur. J. (@chemistryeurope.bsky.social)! Mark's team used DalPhos ligands for Ni-cat. C-P couplings, which we supported with DFT calculations of reductive elimination. doi.org/10.1002/chem... @cathweetman.bsky.social
Nickel‐Catalyzed P‐Arylation of HP(= O)(R/OR)2 Nucleophiles with (Hetero)Aryl Chlorides Enabled by DalPhos Ligation
The development of broadly useful C-P cross-couplings of (hetero)aryl chlorides and HP(O)(R/OR)2 nucleophiles by use of nickel/DalPhos-based catalysts is described, along with findings from DFT studi....

Checkout our new review on advances in Cu and Ni C-N and C-O cross-couplings of aryl chlorides enabled by ancillary ligand development. Such ligand advances offer promise as drop-in replacements for thermal Pd catalysis, without the need for new infrastructure. 😉 dx.doi.org/10.1002/chem....
Advances in Copper and Nickel C‐N and C‐O Cross‐Couplings of (Hetero)Aryl Chlorides Enabled by Ancillary Ligand Development
The evolution of palladium-catalyzed C-N and C-O cross-coupling chemistry into first-choice methods for the synthesis of aniline and phenol derivatives can be attributed to innovations in ancillary l...

Coaching my son’s baseball team and was reminded of this little bit of memorabilia in my garage. As a kid I played AAA baseball (Guelph ON) against Brantford ON (vs Brent Gretzky - he humiliated us in both baseball and hockey) and his brother Wayne would show up to the games to watch him pitch. 1/2
My friend Adrian Raso’s new album is released today - lots of gypsy-jazz bangers! I did the original drum tracks for this album, but the label said “the drums sound like they are from Led Zeppelin” (a compliment 😂 ?) … the redone gypsy drumming sounds great! Enjoy! open.spotify.com/album/30n4Nd...

You can tell they are really throwing it all out there when they start having Harper doing ads for PP. Not the endorsement they think it is 😂
@tsnofficial.bsky.social’s broadcast of the NCAA bball tournament is particularly entertaining when they broadcast the commentators during what must be commercial breaks in the US. Just learned about makeup preferences for covering up a bald head on television😂.
Congrats to Kathleen, Emily, and Erika from our group for their recent report on challenging Ni-catalyzed O-arylation chemistry of pharmaceutical relevance 👍 chemistry-europe.onlinelibrary.wiley.com/doi/full/10....
Nickel‐Catalyzed O‐Arylation of N‐Protected Amino Alcohols with (Hetero)aryl Chlorides

A shout-out to Josh from my group, on his development of a single catalytic manifold for generating benzofurans or indoles selectively. A remarkable effort from a single trainee.👍 pubs.acs.org/doi/10.1021/...
Intercepting Ketone α-Arylation Intermediates in the DalPhos/Ni-Catalyzed Synthesis of Decorated Benzofurans and NH-Indoles
Employing meso-PAd2-DalPhos (meso-L1) as an ancillary ligand, a single mechanistic landscape provides access to two thermal nickel-catalyzed transformations with broad scope commencing from α-(o-chlor...

So excited to share our work on learning more about EAM catalysis on scale! Featuring two of our favorites: nickel and boron 🤓 Who knew there were so many ways to make hydrogen in a borylation reaction 🤪 Congrats to all the co-authors! #BMSChemistry pubs.acs.org/doi/10.1021/...
Development of an Inherently Safe and Scalable Nickel-Catalyzed Borylation Process of an Aryl Sulfamate
A safe and scalable synthesis of A, a key aryl boronate ester intermediate toward an immunology asset udifitimod, via a Ni-catalyzed Miyaura borylation is reported. High-throughput experimentation, design of experiment, and reagent stability/compatibility studies were used to optimize the reaction conditions and furnish the borylation of aryl sulfamate B in 80–85% yield and >98% purity/potency. Significant hydrogen off-gassing was observed during the reaction, metal remediation, and crystallization steps of the first-generation process, and efforts were made to quantify, understand, and mitigate this off-gassing to ensure a safe and reliable scale-up. Two multikilogram batches of the process were successfully run to afford A in an average 85% yield, >99% potency, and ≤28 ppm residual Ni. Using the mechanistic learnings from this work, a second-generation process was developed which significantly reduced hydrogen off-gassing at all steps of the process, as well as increasing final yield and reducing process mass intensity. This second-generation process was demonstrated on a 1 kg scale to afford the product in 90% yield, >99% purity/potency, and 50 ppm residual Ni.

Stradiotto group PDF Kathleen Morrison just back from visiting our collaborator (Charles Yeung) at Merck to learn about HTE and to share her expertise on nickel catalysis 👍
Cerebral palsy should be reframed as “the most common lifelong physical disability,” instead of a childhood disorder, a professor of physical medicine and rehabilitation argues in a recent perspective article for the New England Journal of Medicine.
Why one expert says it’s time to redefine cerebral palsy
Focusing on early detection and prevention has skewed awareness of the permanent nature of the disability, a health expert writes.

Throwing this out there…does anyone know how I can access the following…ideally in English translation? Yagupol'skii J. Org. Chem. USSR 1986, 22, 1547-1554.
Chem-peeps: Do any of you have experience using house N2 to run catalyst enabled gloveboxes? How is appropriate delivery pressure to fire the solenoids achieved, etc? Bad idea? Good idea? 😂
A lovely ligand design paper from the Chirik group 👍 pubs.acs.org/doi/10.1021/...
