The first paper from Khaled’s PhD research has been accepted for publication by Green Chemistry.
It is called “Hydrolysis of Chitosan Into Levulinic Acid and 5-Hydroxymethylfurfural In Water Under Microwave Irradiation”
It describes our first efforts at converting biopolymers that can be obtained from fishery waste into potentially useful small molecules. This proof of concept will hopefully lead to these natural materials being used alongside agricultural and forestry wastes as the starting point for chemicals with a wide range of purposes including, fuels, agrochemicals, pharmaceuticals and plastics.
Some of the results were obtained in collaboration with Jessica Besaw (NSERC USRA 2010, Kerton group) who Khaled acted as mentor to. Congratulations Khaled and Jess!
Aminopolysaccharides (Chitin) are available in the shells of crustaceans (lobsters, crabs, shrimps). Khaled has shown that valuable 'Platform' chemicals can be made from them

Further to work being patented by their respective Universities and GreenCentre Canada, results on controlled radical polymerization using iron amine-phenolate complexes has been accepted for publication in Macromolecular Rapid Communications, DOI: 10.1002/marc.201100872 Congratulations to the Kozak (MUN) and Shaver (UPEI) groups.
Charlotte Willans (PhD with Dr. Kerton, 2004) has obtained exciting results in the field of chemotherapy. Her work on silver carbene complexes has been published in Dalton Transactions. It has been featured in the UK Newspaper “The Daily Mail” and she was interviewed on Radio 4 (National UK radio) this morning. Congratulations Charlotte!
Zhenzhong’s (Kerton group) copper coordination chemistry paper “Coordination chemistry of α-ω-di(pyridyl-imine) ligands containing flexible linkers with copper(I)” has been accepted for publication in the European Journal of Inorganic Chemistry. Special thanks to Louise Dawe for the X-ray structural determination and Celine Schneider for solid-state NMR and diffusion studies.
Rebecca and Kamrul (Kozak group) and a suite of collaborators have had their iron coordination chemistry paper accepted by Dalton Transactions: “Magnetic, electrochemical and spectroscopic properties of iron(III) amine-bis(phenolate) halide complexes”
Congratulations to them all and here’s to many more excellent publications in 2012!
Congratulations to Lisa (BSc Hons student), Nduka (PhD candidate and mentor), Chad (Former undergraduate research assistant in Kerton group – now at MUN medical school) and Uttam (Former MSc student, now PhD candidate at UOttawa). Also, thank you to Louise Dawe for her continued X-ray crystallography collaborations with our groups.
The paper is titled “Coupling of Carbon Dioxide with Neat Propylene Oxide Catalyzed by Aminebisphenolato Cobalt(II)/(III) Complexes and Ionic Co-catalysts” and has been accepted for publication in Catalysis Communications (published by Elsevier). Well done everyone!
Zhenzhong’s full paper (8 pages) titled “Simple copper/TEMPO catalyzed aerobic dehydrogenation of benzylic amines and anilines” has been accepted for publication in Org. Biomol. Chem., DOI:10.1039/C2OB06670J. It should be available online soon.
Graphical Abstract / Table of Contents Entry for the article
Chris Kozak and his collaborator Mike Shaver at UPEI have recently submitted a patent application for iron catalysts and their use in C-C cross-coupling and controlled radical polymerization. The work is being evaluated for further development and partnerships through GreenCentre Canada, MUN and UPEI.
Zhenzhong’s research on alcohol oxidation catalysis has been accepted for publication in Applied Catalysis A: General (published by Elsevier). Congratulations to him!
Prof. Phil Jessop (Queen’s University, Kingston, ON) visited the department yesterday, gave a talk on switchable surfactants and spent some time with our group. We’ve already had lots of great feedback from students and faculty – so even more new ideas and uses for switchable materials are on the horizon. Thank you Phil!
Many of the group will be attending the IYC/Chemistry Week event “Caffeinating with Chemists” at the Rocket on Water Street in St. John’s this evening. Fran will be giving a short presentation on Green Chemistry subtitled ‘It’s not easy being green or is it?’
