Reference excerpt

Igor Guerrero Larrosa is a Spanish chemist and a professor in the Department of Chemistry at The University of Manchester. His research in general is based on organic chemistry and inorganic chemistry, specifically on the areas of inorganic catalysis and organic synthesis including the application to C-H and decarboxylative activation.

Education Larrosa completed his Bachelor of Science degree in 1999 at University of Barcelona. He continued to read for his Master of Science and Doctor of Philosophy at University of Barcelona under the supervision of Dr. Fèlix Urpí Tubella and Dr. Pedro Romea García and successfully completed his PhD in 2004.

Research and career Upon completing his PhD, Larrosa received a three months fellowship from the Ministry of Education and Science, Spain to work with Erick M. Carreira at ETH Zürich before moving to Imperial College London for a postdoctoral research with Prof. Anthony Barrett. He then moved to Queen Mary University of London as a lecturer and was promoted to the position of senior lecturer and reader in 2011 and 2012 respectively. In 2014, he moved to the University of Manchester as a professor of organic chemistry. Larrosa's research in general is based on organic chemistry and inorganic chemistry, specifically on the areas of inorganic catalysis and organic synthesis including the application to C-H and decarboxylative activation. Larrosa received an EPSRC in 2011 and currently holds an EPSRC Advanced Grant. He is also a member of 2D, a research programme in the aim of bringing together a team of multi-disciplinary researchers as well as world-leaders in G2D research.

Notable work Larrosa is considered as one of the world's leading researcher's in Carbon–hydrogen bond activation. C – H bonds in organic compounds are particularly un-reactive due to the strong bonds between the carbon and hydrogen atoms and such bond activation would increase the reactivity and therefore enable the potential development of novel organic compounds. Larrosa's research has showed how transition metal catalysis maybe used to achieve C – H bond activation, and for his efforts in the field, was awarded the Corday-Morgan Prize and was a finalist at the Blavatnik Awards (UK) in 2019. The published research also have shown the enhanced regioselectivity and stereoselectivity in these catalysis processes, which is generally difficult to be achieved in this field. Apart from research based on C – H bond activation, Larrosa has also published several research on decarboxylation and arylation reactions.

Worked examples

Example 1 — a first encounter with Igor Larrosa

Start with the simplest possible case. Write down what Igor Larrosa claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Igor Larrosa before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Igor Larrosa ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Igor Larrosa

In research: Igor Larrosa appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Igor Larrosa in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Igor Larrosa is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century chemists, Academics of the University of Manchester, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Igor Larrosa outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
