Abstract Since 1963, when Karl Ziegler and Giulio Natta were jointly awarded the Nobel
Prize for their discoveries of the catalytic polymerization of olefins with Ti-chlorides and Al …

Organometallic chemistry has provided the foundation for the development of a wide range
of new olefin polymerization catalysts over the last two to three decades. The unraveling of …

Catalytic methods that introduce functional groups via carbon–carbon bond cleavage steps
have typically been limited to moieties activated by strain or by directing groups, with few …

Activation of Cp2ZrCl2 and Cp2ZrMe2 by methylaluminoxane (MAO) in toluene is largely
complete at Al: Zr ratios of 100: 1 to 200: 1 as revealed by electrospray ionization mass …

The power of natural selection through survival of the fittest is nature's ultimate tool for the
