High Conversion of Styrene, Ethylene, and Hydrogen to Linear Monoalkylbenzenes

Autor: David Hermann Lamparelli, Antonio Ricca, Vincenzo Palma, Leone Oliva

Publikováno v: Molecules, Vol 23, Iss 6, p 1260 (2018)

1-Alkylbenzenes as a precursor of surfactants, can be produced from ethylene, styrene, and hydrogen. These intermediates, lacking tertiary carbons, are environmentally more benign than commercial ones that bear the aromatic ring linked to an internal

C–H Activation and Olefin Insertion as Sources of Multiple Sites in Olefin Polymerization Catalyzed by CpAlkylHf(IV) Complexes

Autor: Alceo Macchioni, Roger L. Kuhlman, Leonardo Tensi, Cristiano Zuccaccia, Anthony P. Gies

Publikováno v: ACS Catalysis. 7:563-567

Intramolecular activation of hydrocarbyls to form metallacyclic complexes is a relatively fast process in cationic hafnocene catalysts bearing propyl-substituted Cp ligands. The resulting metallacycles are effective 1-hexene polymerization catalysts
