Dinuclear Group 4 Metallocene Catalysts of the Type [(Cp2M)2(μ‐Me)(μ‐C2R)]: Structure‐Activity Relationships in Ethylene Polymerization

Chemistry – A European Journal, EarlyView.
Homo‐ and heterodinuclear group 4 metallocene complexes of the type [(Cp2M)2(μ‐Me)(μ‐C2R)] (M = Ti, Zr) are active catalysts for the polymerization of ethylene in the presence of aluminium‐free activators. The catalytically active species are proposed to have dinuclear character and depending on the type of activator, unique reactivity was observed ...

Catalytic Generation of Cationic Gold Carbene Complexes From 7‐Alkynylnorbornadienes and Their Intermolecular Cyclopropanation With Alkenes

Chemistry – A European Journal, EarlyView.
Efficient cationic gold(I)‐catalyzed intermolecular cyclopropanation of 7‐alkynylnorbornadiene derivatives has been developed. This methodology offers the synthesis of a new class of norbornene derivatives in high yield with excellent diastereoselectivity.

Synthesis and Biological Evaluation of Well‐Defined M6P(n)‐Modified Glycopeptides for Targeted Protein Degradation

Chemistry – A European Journal, EarlyView.
A synthetic methodology has been developed to prepare multifunctional M6P and M6Pn ligands of different valency. The glycopeptides were conjugated to cetuximab and then examined to mediate cellular uptake of fluorescently labeled EGFRvIII. Only cetuximab modified by glycopeptides having 3 or 6 M6P or M6Pn residues demonstrated greater uptake.

Covalent Insertion of a Mn(Salen) Type Complex in Cross‐Linked Protein Crystals: Design of an Enantioselective Artificial Epoxidase

Chemistry – A European Journal, EarlyView.
An Artificial metalloenzyme was designed by a Michael addition between a MnSalen complex and a cysteine residue within NikA crystals. The heterogeneous catalyst was found capable of an enantioselective and stereospecific epoxidation of cis‐β‐methylstyrene in cristallo.

A novel bubbling fluid bed reactor for the autothermal pyrolysis of waste plastics

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract A new pilot‐scale fluidized bed reactor operated under continuous conditions was developed and tested for the thermal pyrolysis of high‐density polyethylene (HDPE). The study focused on assessing the reliability and operability of the system under different operating conditions (400–550°C), while monitoring mass and energy balances, product ...
