Muñoz Molina, José María; Rodríguez Belderraín, Tomás; Pérez Romero, Pedro José (Elsevier, 2019)
Tris(pyrazolyl)borates (Tpx) have become one of the most broadly used polydentate anionic ligands in coordination chemistry and catalysis since Trofimenko introduced them in 1966. Herein we present a review of the main ... -
Dimensioning the term carbenoid
Caballero Bevia, Ana; Pérez Romero, Pedro José (Wiley, 2017)
The current use of the term carbenoid is discussed, particularly in the context of carbene transfer reactions from diazo compounds, where intermediates of type LnM=CR1R2, or one of its resonance forms, are tagged which ... -
