Favoring alkane primary carbon-hydrogen bond functionalization in supercritical carbon dioxide as reaction medium
Sarmiento, Jeymy T.; Olmos Verge, Andrea; Rodríguez Belderraín, Tomás; Caballero Bevia, Ana; Varea, Teresa; Pérez Romero, Pedro José; Asensio, Gregorio (American Chemical Society, 2019)
The selectivity of a catalytic alkane functionalization process can be modified just changing the reaction medium from neat alkane to supercritical carbon dioxide (scCO2). A silica supported copper complex bearing an ... -
Group 11 tris(pyrazolyl)methane complexes: structural features and catalytic applications
Muñoz Molina, José María; Rodríguez Belderraín, Tomás; Pérez Romero, Pedro José (Royal Society of Chemistry, 2019)
Tris(pyrazolyl)methane ligands (Tpmx) have been for years a step behind their highly popular boron-anionic analogues, the tris(pyrazolyl)borate ligands (Tpx). However, in the last decade the development of new members of ... -
