Steric Control of Sorting Regimes in Self-Assembled Cages

Control of self-sorting regimes is achieved through adjustment of steric interactions in self-assembled coordination cages. The self-assembly regime of dynamic mixtures of heteroleptic cages is followed by HPLC to show...

Transition metal-mediated B(4)–H hydroxylation/halogenation of o-carboranes bearing a 2-pyridylsulfenyl ligand

Regioselective rhodium-induced B(4)–H hydroxylation and halogenation reactions of o-carboranes are reported. The key intermediate has been isolated. Iridium-induced B(3)/B(4)–H activation of o-carboranes has been achieved through steric control.

Sterically controlled reductive oligomerisations of CO by activated magnesium(i) compounds: deltate vs. ethenediolate formation

Subtle changes to the bulk of 1 : 1 adducts of DMAP with magnesium(i) complexes leads to steric control over the products arising from their reductive oligomerisations of carbon monoxide.

Vibrational circular dichroism towards asymmetric catalysis: chiral induction in substrates coordinated with copper(ii) ions

The VCD method was applied for searching the origin of chirality selection in the asymmetric catalysis by Cu(ii) complexes. When 1-phenyl-1,3-butanedionato was coordinated, it was transformed to a twisted chiral form under the steric control.
