El Instituto CINQUIMA de la Universidad de Valladolid recibe este martes, 5 de febrero, al profesor Nilay Hazari, de la Universidad de Yale, que impartirá la conferencia “The Rational Development of Precatalysts for Cross-Coupling and Cross- Electrophile Coupling Reactions”.

El Grupo Especializado de Química Organometálica de la RSEQ ha organizado la estancia de Hazari como  Conferenciante Itinerante durante el mes de febrero en España, y, desde el CINQUIMA, nos ha parecido interesante invitarle a impartir una conferencia en Valladolid.

La conferencia tendrá lugar a las 12:00 h en la sala de conferencias del Edificio QUIFIMA.

La entrada es libre hasta completar el aforo.

Abstract:

Transition metal catalyzed cross-coupling has found applications in diverse areas of chemistry and is
widely considered to be one of the most powerful and general synthetic methods. Both Ni and Pd
complexes are now commonly used to facilitate cross-coupling reactions. The mechanism for both Ni and
Pd catalysts is typically proposed to involve a series of complexes in the M(0) and M(II) oxidation states.
In this presentation we will describe results that indicate that state-of-the-art Ni and Pd precatalysts form a
significant quantity of species in the M(I) oxidation state during catalytic reactions. We will describe the
mechanistic pathways through which these M(I) complexes are formed. The M(I) complexes are
catalytically inactive and by understanding how they are formed it is possible to stop their generation
during catalysis. We have used this information to design improved catalytic systems, which are now
commercially available. The implications of our results to crosselectrophile coupling will also be explored.
 
Short CV:
Nilay Hazari was born in Suva, Fiji and spent the first 17 years of his life in Melbourne, Australia. After
that he moved to Sydney where he received a B.Sc (2002) and an M.Sc (2003) from the University of
Sydney working with Professor Leslie D Field. He completed a D.Phil (2006) as a Rhodes Scholar at the
University of Oxford under the supervision of Professor Jennifer C Green and then worked for three years
as a postdoctoral scholar with Professors John E Bercaw and Jay A Labinger at the California Institute of
Technology. Nilay began as an Assistant Professor of Chemistry at Yale University in July 2009 and is
currently a Professor of Chemistry.
