Green Chemistry @ MUN


Two papers accepted on the same day!

Yesterday, the profs got good news from the publishers 😀

Dr. Kerton’s paper was accepted by Organometallics and Dr. Kozak’s paper was accepted by Dalton Transactions.

The Organometallics paper is about the synthesis and reactivity of some aluminum complexes. Some of the compounds were prepared for the first time by Marcus Drover (during his SWASP in summer 2010) and Stephanie Barbon (in summer 2011 as an NSERC USRA/ICE student). Kinetic studies were performed by Nduka on their activity in ring-opening polymerization of caprolactone. He also discovered that the chloride complex could initiate the copolymerization of carbon dioxide and cyclohexene oxide. http://dx.doi.org/10.1021/om300757u

The Dalton Transactions paper contains research results from Rebecca’s PhD thesis on copolymerization of carbon dioxide with propylene oxide and addition reactions between styrene oxide and carbon dioxide. This is the second paper published from the Kozak group Cr catalysts for this reaction (Paper 1: Inorg. Chem. 2012) and also builds on results obtained using related Co complexes (Catalysis Communications 2012).

A big thank you to Louise Dawe for her expertise in X-ray crystallography and to all the students involved!

Al complexes for ring-opening polymerization of caprolactone and activation of carbon dioxide



Congratulations to Nduka and Christian!

A second paper by group members has been accepted today for publication. This time in Dalton Transactions.

The paper is called: Ring-opening polymerization of ε-caprolactone by lithium piperazinyl-aminephenolate complexes: Synthesis, characterization and kinetic studies

Dalton Trans., DOI:10.1039/C2DT30276D

Nduka is a PhD candidate in our group and Christian was a visiting student from Germany who joined our group last summer on a DAAD RISE scholarship.  They worked really hard to get all the kinetic data and the MALDI-TOF spectra presented in this paper. Thanks also to Louise for the two structures included.
