# Mark Stradiotto

Mark Stradiotto is a Canadian chemist. He is currently the Arthur B. McDonald Research Chair (CRC Tier-I equivalent) and the Alexander McLeod Professor of Chemistry in the Department of Chemistry at Dalhousie University.

## Education and academic career

Stradiotto received his BSc (Hons.) in applied chemistry (1995) and PhD in organometallic chemistry (1999) from McMaster University, the latter under the supervision of Michael A. Brook and Michael J. McGlinchey. After conducting research as an NSERC Postdoctoral Fellow at the University of California at Berkeley with T. Don Tilley (1999–2001), Stradiotto moved to the Department of Chemistry at Dalhousie University where he now holds the rank of Professor with tenure. In July 2013, Stradiotto was named the Alexander McLeod Professor of Chemistry, and in 2017 he was named a Fellow of the Royal Society of Chemistry (UK). In 2020 he was named an Arthur B. McDonald Research Chair (CRC Tier-I equivalent; 2020–2027). In 2021, Stradiotto was awarded the Canadian Society for Chemistry Rio Tinto Award, for distinguished contributions to the field of inorganic chemistry in Canada.

## Research contributions

Stradiotto’s research is directed toward developing new classes of ancillary ligands/transition metal complexes that exhibit interesting and unusual reactivity patterns, with the goal of incorporating such reactivity into synthetically useful catalytic substrate transformations that can be employed by end-users in both academic and industrial settings. In particular, he is best known for developing the "DalPhos" (DALhousie PHOSphine) ligand family and derived catalyst systems for palladium and nickel cross-couplings that are of relevance to the pharmaceutical industry, many of which have been commercialized. Reported DalPhos ligands and their substrate applications include:
* Ni/CgPhen-DalPhos (tertiary alcohols)
* Ni/PhPAd-DalPhos (sulfonamides, bulky primary alkylamines)
* Ni/Phen-DalPhos (heteroaryl amines, ammonia, indole)
* Ni/PAd2-DalPhos (heteroaryl amines, fluoroalkylamines)
* Ni/NHP-DalPhos (primary alkylamines)
* Ni/CyPAd-DalPhos (primary and secondary aliphatic alcohols, cyclopropylamine and variants)
* Ni/PAd-DalPhos (ammonia and primary alkylamines)
* Pd/Mor-DalPhos (ammonia)
