Tuākana Science is a multi-faceted programme for Māori and Pacific students providing topic specific tutorials,
one-on-one sessions, test and exam preparation and more. Explore your options at
As part of the University-wide Tuākana community, The School of chemical sciences aims to provide a welcoming learning environment for and enhance the success of, all of our Māori and Pacific students. We are led by the principles of tautoko (support) and whanaungatanga (connection) and hope you find a home here at the School. Students who have identified as Māori and/or Pacific will receive an invitation to our online portal introducing the Programme, the resources we have available, and how you can get involved.
Tuākana Chemistry runs a range of activities for students enrolled in this class. This includes weekly workshops, social activities, and opportunities to engage with senior students and researchers within the School of Chemical Sciences. Tuākana-eligible students will be added automatically to the Tuākana Chemistry program when they enroll in this course. For more information, please see the Tuākana program website or email firstname.lastname@example.org.

(B) Green Organic synthesis (8 lectures)
Advantages over traditional functional group manipulations.
The selective reaction of Csp2-H and Csp3-H bonds; radical and transition metal-mediated processes, use of directing groups and auxiliaries.
Iridium catalyzed C-H borylation processes in heteroaromatic C-H functionalization and relevance to the pharmaceutical industry
Hydrogen auto-transfer (borrowing hydrogen)
Alternative to alkylating agents (R-Br, ROTs, etc.)- using safe, non-toxic alcohols as ‘electrophiles’, facile transition metal-mediated functionalization of amines (C-N bond formation) and C-C bond formation is possible. Applications of borrowing hydrogen methodology in pharmaceutical synthesis are discussed.
Renewable feedstocks, recycling
Production of renewable feed-stocks, sustainability of commercial growing practices, sources of waste that potentially could be utilized to make valuable products, assessment of the full costs of utilizing waste and recycling vs alternative of dumping, burning, etc., sustainability considerations. Examples could include: Converting agri-waste to valuable products (e.g. winery waste to packaging etc.), developing a fully recyclable carpet; (and use of polymers that can be recycled).
(C) Sustainability and the pharmaceutical industry: (4 lectures)
Introduction: Importance of active pharmaceutical ingredients (APIs) to our health, misuse of APIs – over prescription, factory farming, and antibiotic use, antibiotic resistance, etc, typical characteristics designed for current active pharmaceutical ingredients (AOIs), how these characteristics (bio-availability, bio-active, resistance to being metabolized, etc) lead to problems when the APIs are released into the environment, APIs that are found in drinking water, inefficient syntheses of many pharmaceuticals (waste produced per kg product). Selected examples of some of these features.
(D) Biocatalysts (6 lectures)
Introduction: Advantages and challenges of using biocatalysts in green chemistry, with a particular focus on the different immobilization techniques to improve enzyme biocatalysts. The use of multienzyme systems in biocatalysis and in the degradation of environmental pollutants will also be discussed.
(E) Solar energy and alternative solvents (8 lectures)
Solar energy: Modern societies are heavily reliant on cheap fossil fuel energy for electricity generation and transportation. Dwindling fossil fuel reserves and environmental concerns associated with anthropogenic CO2 emissions from fossil fuel use motivate the development of alternative and sustainable renewable energy technologies. These lectures will explore the generation of energy from solar power sources following;
Solar Power: Total solar energy available in practice, the diurnal problem
• capturing solar energy as thermal energy,
• Mechanism of solar cell operation and capturing solar energy as electrical energy (photovoltaics, dye-sensitized solar cells, organic solar cells),
The pros and cons of solar capture technologies will be considered within a sustainability context.
Solvents are a substantial component of chemical waste and can introduce hazards such as toxicity and flammability to chemical processes. However, the effect of solvents on the outcomes of chemical processes is often underappreciated in the search for alternatives. This lecture series will explore recent developments in the design and development of environmentally benign ‘smart’ solvents including concepts such as deep eutectic solvents and switchable polarity solvents.
