Noncovalent Immobilization of Cationic Ruthenium Complex in a Metal–Organic Framework by Ion Exchange Leading to a Heterogeneous Olefin Metathesis Catalyst for Use in Green Solvents
A simple strategy for noncovalentimmobilization of an olefin metathesiscatalyst inside a (Cr)MIL-101-SO3Na metal–organic framework (MOF) was presented. The olefin metathesis active core—an alkylidene complex bearing an ammonium-tagged NHC ligand (Apeiron’s FixCat)—was immobilized by ion exchange facilitated by the use of crown ether. The hybrid material thus obtained was shown with a number of model

Indirect Electroreductive Cyclization of N-Allyl and N-Propargylamides Using a Nickel(II) Complex as an Electron-Transfer Catalyst: Selective Formation of Halogenated and Non-halogenated Pyrrolidinones.
Nickel(II) complex-catalyzed indirect electroreduction of N-allyl and N-propargyl-α-bromoamides conducted in dimethylformamide with 2 eq of a hydrogen atom donor, diphenylphosphine, afforded the corresponding pyrrolidinones as the sole cyclized product in good yields, while that of N-allyl-α-iodoamides in acetonitrile gave the iodinated pyrrolidinones. Under both conditions the trans-C-3 : C-4 pyrrolidinones were formed predominantly.

phtotpolymerisable hole-transport layers based on novel triazatruxenes incorporating six non-conjugated dienes as photo cross-linkable end-groups attached to flexible, aliphatic spacers have been synthesised using simple one-step substitution reactions. Hole-only test devices, fabricated using a combination of solution-deposition, spin-coating and initiator-free photochemical cross-linking of these photopolymerisable
