Inicio: Martes, 05 febrero 12:00
Fin: Martes, 05 febrero 14:00 - Edificio QUIFIMA. Campus Miguel Delibes de la Universidad de Valladolid
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 iswidely considered to be one of the most powerful and general synthetic methods. Both Ni and Pdcomplexes are now commonly used to facilitate cross-coupling reactions. The mechanism for both Ni andPd 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 asignificant quantity of species in the M(I) oxidation state during catalytic reactions. We will describe themechanistic pathways through which these M(I) complexes are formed. The M(I) complexes arecatalytically inactive and by understanding how they are formed it is possible to stop their generationduring catalysis. We have used this information to design improved catalytic systems, which are nowcommercially 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. Afterthat he moved to Sydney where he received a B.Sc (2002) and an M.Sc (2003) from the University ofSydney working with Professor Leslie D Field. He completed a D.Phil (2006) as a Rhodes Scholar at theUniversity of Oxford under the supervision of Professor Jennifer C Green and then worked for three yearsas a postdoctoral scholar with Professors John E Bercaw and Jay A Labinger at the California Institute ofTechnology. Nilay began as an Assistant Professor of Chemistry at Yale University in July 2009 and iscurrently a Professor of Chemistry.-
