APPLICATIONS OF ORGANOMETALLIC, TRANSITION AND MAIN GROUP CHEMISTRY - 2024/5
Module code: CHEM039
The module is designed to build upon knowledge from Inorganic modules at level 4, 5 and 6. This is achieved by introducing areas of inorganic chemistry that have not been addressed previously and by expanding towards the applications of topics that were previously introduced. The aim is to develop an advanced understanding of Organometallic chemistry and its applications in homogeneous catalysis, involving both d-block transition metals and main group elements.

|Assessment type||Unit of assessment||Weighting|
|Examination Online||ONLINE OPEN BOOK 4 hour EXAM||80|
The assessment strategy is designed to provide students with the opportunity to demonstrate:
- A detailed understanding of the synthesis, structure, and bonding in organometallic compounds of both transition metals and main group elements.
- A general understanding of the application of organometallic compounds to problems in homogeneous catalysis.
- An understanding of modern approaches to homogeneous catalysis
This is achieved through a coursework question set / research paper analysis and open book examination that pose advanced problem-based questions, often stemming from issues in the research literature. This provides an opportunity to use fundamental and advanced knowledge to critically address problems in a authentic way.
Thus, the summative assessment for this module consists of:
Coursework, 20%, problems & research analysis (addresses learning outcomes 1 to 5)
Examination, 80%, online open book 4 hours (addresses learning outcomes 1 to 4)
The teaching methods include tutorials that are spaced throughout the semester and appear at the end of each major topic: introduction to organometallic chemistry, heterogeneous catalysis, carbonyl clusters, main group organometallics. These sessions are used to give the students practice at solving problems relating to the taught topics, of a similar nature to those found in the coursework and examination.
The tutorial and revision sessions will be used to verbally feedback to the students on their approach to the problems discussed in these sessions.
- To introduce the fundamental theory of structure and bonding in d-block and main group organometallic chemistry, including Hoffman¿s Nobel prize winning work on isolobal theory.
- To illustrate the synthesis and reactivity of selected d-block and main group organometallic compounds
- To investigate advanced topics in the application of organometallic d-block and main group compounds with a focus on homogeneous catalysis.
- To outline specialized topics in homogenous catalysis such as metal-ligand cooperativity in main group complexes.

Methods of Teaching / Learning
The learning and teaching strategy is designed to:
- Allow each student to expand on their knowledge from level 4,5 and 6 Inorganic modules to understand the connection between inorganic and organic chemistry through the topic of organometallic chemistry.
- Provide the student with an insight into the application of organometallic chemistry in the industrially relevant area of homogeneous catalysis.
- Improve a student’s understanding of the bonding, structure and reactivity of s, p and d-block compounds and to apply this knowledge to solve problems in synthesis and structure elucidation.
- Allow student’s to show a critical approach to interpretive data
The learning and teaching methods include:
- Tutorials and directed learning
- Revision classes
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.

The School of Chemistry and Chemical Engineering is committed to developing graduates with strengths in Employability, Digital Capabilities, Global and Cultural Capabilities, Sustainability, and Resourcefulness and Resilience. This module is designed to allow students to develop knowledge, skills, and capabilities in the following areas:
One of the major topics in this module is the chemistry and mechanism of action of heterogeneous catalysts based on organometallic compounds. Understanding this topic will allow the student to see how the efficiency and energy consumption of chemical reactions can be improved: a major factor in approaches to Sustainability. This subject is a major area of Industrial research and activity, thus providing knowledge and skills directly relevant to Employability. Student’s will need to use specialist software, introduced at level 4, to construct answers to problems, which will maintain each student’s Digital Capabilities. Students will also be directed to use specialized web-pages that provide 3D views of molecules and focus on symmetry.
