Currently the Mulvey group is developing the special synergistic chemistry that can be created through combining distinct components (mixtures of different metals and different ligands) within the same molecular environment. Fundamentally it could be said that mixing two distinct metal compounds, for example a lithium amide and a magnesium bisalkyl, produces a heterometallic molecule which acts neither as a lithium nor a magnesium compound but a compound of a unique new metallic element! Novel chemistry, beyond the scope of conventional homometallic reagents, is the reward. This idea has been applied to metallation chemistry. Metallation (transforming inert C-H bonds to reactive, useful C-Metal bonds) is one of the most important bond-making tools in chemistry, used routinely in synthetic laboratories worldwide, and increasingly employed from milligram to ton scales in fine chemical and pharmaceutical manufacture. In alkali-metal-mediated metallation the alkali metal is the catalyst while the formally less reactive metal (for example, magnesium or zinc) executes the deprotonation (low polarity metallation). Major challenges are to turn stoichiometric metallation reactions into catalytic processes and to invent ways of achieving unusual regioselectivities across a broad range of substrates.

Robert Emmet Mulvey was born in Glasgow, Scotland in 1959. He received his first degree (BSc. in Chemistry with 1st class Honours) and his Ph.D. (in organolithium chemistry under the direction of Dr Ron Snaith) at the University of Strathclyde in 1981 and 1984 respectively. Following two years as a postdoctoral fellow at the University of Durham (in the group of Professor Ken Wade), he returned to Strathclyde in 1986 and was promoted to a Professorship in 1995. To date he has published over 250 research papers and several book chapters. Exceeding £3M in total as PI, his career research income includes over £2.1M from EPSRC. A Fellow of the Royal Society of Edinburgh (FRSE), his research on polar organometallic chemistry has won him several awards and prizes as detailed below. Most recently his work was honoured by the GDCh Arfvedson Schlenk Prize for 2013, awarded for “outstanding achievements in discovering synergistic effects of mixed main group metal compositions”. Previously on the international advisory board of the ACS journal Organometallics, he joined the editorial board of Chemistry – A European Journal in 2014.

(Opposite to the “sedation” story in the Science paper, switching to a different bimetallic reagent leads to a catastrophic cleavage of THF, breaking 6 of its 13 bonds.

(Previously no known organomagnesium reagent could deprotonate a metallocene, but here using a synergic sodium-magnesiate reagent, ferrocene could be deprotonated not once but four times. The outcome of this remarkable regioselective tetramagnesiation was a new 16-membered inverse crown ring structure).

- "Polar organometallic chemistry provides an essential toolkit for transforming inert bonds into reactive bonds to make new compounds and materials. Very few aromatic molecules (e.g., pharmaceuticals, agrochemicals, perfumes) are made without polar organometallic chemistry being practiced at some stage in their manufacture. Though this chemistry has a long and successful history, it is currently at an exciting crossroads in its development with seemingly impossible challenges within it now on the verge of becoming possible. This project is designed towards fundamentally reforming the practice of polar organometallic chemistry making it more air and moisture compatible, greener, more atom-economical and sustainable. Research will focus on the synthesis, cultivation and exploitation of new s-block metal multicomponent reagents made by co-complexation protocols. Preliminary work has shown that mixing different components within the same environment (for example, two distinct metal complexes; or one metal but with an assortment of ligands) can lead to useful synergistic effects not possible with unmixed systems. The scope of the chemistry and the ability to construct new compounds and new materials to meet societal needs are thus greatly broadened.
Based on earth-abundant metals, these co-complex reagents will be screened in key organic transformations, focusing on deprotonative metallation and metal-halogen exchange reactions as well as in tandem C-C bond forming methods (as an alternative to more expensive and less environmentally benign transition-metal-mediated approaches) targeting synthetically relevant organic substrates. Stoichiometric reactions will be upgraded to catalytic regimes to establish the ground rules for s-block synergistic catalysis focusing on intramolecular hydroamination reactions of a range of unsaturated molecules.
A key objective of the project is to pioneer and extend the use of multicomponent polar organometallic reagents in Deep Eutectic Solvents (DESs). These DESs will provide more cost-effective, greener and biorenewable reaction media to those volatile organic solvents (VOC's) in which most polar organometallic chemistry is carried out today. Progress in this aim will go a long way to eventually realising the impossible challenge in polar organometallic chemistry of synthesising and utilising chemoselective organometallic reagents under air and/or in aqueous media. Dispensing with the need for a dry inert atmosphere would have genuine worldwide implications for the practice of polar organometallic chemistry both in academia and industry."
