Miguel A. Esteruelas was born in Zaragoza and grew up in La Zaida, a small village situated on the banks of the Ebro. He attended University of Zaragoza where received his Diploma in Chemistry in 1981. He carried out his doctoral work in organometallics at University of Zaragoza under the direction of Professors Daniel Carmona and Luis A. Oro. After obtaining his Ph.D. in December 1983, he worked as a postdoctoral fellow in the laboratory of Prof. Helmut Werner at the University of Würzburg, for 18 months. In 1985, Esteruelas returned to the University of Zaragoza, where he was promoted to Professor of Inorganic Chemistry in 1988 and to Distinguished Professor in 2003. In 2007, he moved to the Spanish Research Council (CSIC), where he is currently Research Professor at the Instituto de Síntesis Química y Catálisis Homogénea (ISQCH). Esteruelas’ research group focuses its interest in mechanistic, synthetic, and structural organometallic chemistry. Emphasis has been placed on the use of transition metal hydride complexes for the activation of σ-bonds, the generation of metal–carbon multiple bonds, and the catalytic formation of carbon–carbon and carbon–heteroatom bonds.
