TL;DR: Five examples of selectively fluorinated unsymmetrical diiminoacenaphthylene-nickel catalysts, incorporating a high fluorine content on one N-aryl group, display superior productivity.
Bonding in pentalene complexes and their recent applications
TL;DR: In this paper, molecular orbital theory is used to describe the bonding in transition metal pentalene complexes in a variety of its coordination modes, and various MO models account for structural parameters and lead to simple rules for electron counting.

TL;DR: Delamination of LDHs is an interesting route for producing positively charged thin platelets with a thickness of a few atomic layers, which can be used as nanocomposites for polymers or as building units for making new designed organic- inorganic or inorganic-inorganic nanomaterials.

Stereospecific Olefin Polymerization with Chiral Metallocene Catalysts
TL;DR: In contrast to heterogeneous Ziegler-Natta catalysts, homogeneous metallocene-based catalysts as discussed by the authors allow efficient control of regio-and stereoregularities, molecular weights and molecular weight distributions, and comonomer incorporation.
