Organocatalytic synthetic route to esters and their application in hydrosilylation process

Scientific Reports
A facile esterification of α,β-unsaturated aldehydes with alcohols has been developed for the synthesis of esters by using bulky N-heterocyclic (NHC) carbene as a metal-free and eco-friendly organocatalyst.

Hydrodenitrogenation of pyridines and quinolines at a multinuclear titanium hydride framework

Nature Communications, 2017
Hydrodenitrogenation is a fundamental process in the petroleum refinery context. Here, the authors report the mild ring-opening and denitrogenation of pyridines and quinolines with a titanium hydride cluster and the unusual formation of denitrogenated ...

A Catalytic Osmium Redox Couple Collapses Cancer Redox Balance

Advanced Science, EarlyView.
A stable Os(III)/Os(IV) redox couple is developed to disrupt the tumor cell redox balance by concurrently catalyzing ROS generation and GSH depletion. Osmium‐treated cells exhibit multiple cell death pathways, including apoptosis, ferroptosis, and immunogenic cell death.

Site‐Selective B─H Activation via HAT Toward Xanthyl‐closo‐Carboranes as Bench‐Stable Precursors of Organosulfur Boron Clusters

Angewandte Chemie, EarlyView.
A light mediated direct regioselective B─H functionalization, via hydrogen atom transfer (HAT), is described. Unexplored xanthyl‐closo‐carboranes as novel bench‐stable and versatile platforms to access sulfur‐containing boron clusters are reported for the first time.

Structure and Spectroscopic Characterisation of Phenanthroline‐Based Iodobismuthate(III) Complexes Utilised for Raw Acoustic Signal Classification

Advanced Intelligent Discovery, EarlyView.
Memristors based on trimethylsulfonium (phenanthroline)tetraiodobismuthate have been utilised as a nonlinear node in a delayed feedback reservoir. This system allowed an efficient classification of acoustic signals, namely differentiation of vocalisation of the brushtail possum (Trichosurus vulpecula).

Tandem Reactivity of Metal−Carbon and Carbon−Silicon Bonds in Mononuclear α‐Silyl Organolithium or Organosodium Complexes Towards CO, CO2 and Heteroallenes

Angewandte Chemie, EarlyView.
Anionic α‐silyl alkyl is one of the most used organometallic building blocks and funtional groups. Traditionally, the C─Si bond in these complexes is considered as inert. In this work, we report a series of reactions between mononuclear organo‐lithium and ‐sodium complexes with CO, CO2, or heteroallenes.

Organometallic and Bioorganometallic Chemistry - Ferrocene and Metal Carbonyls [PDF]

Kemija u Industriji, 2011
Organometallic chemistry deals with compounds containing metal-carbon bonds. Basic organometallics derived from the s- and p-block metals (containing solely σ-bonds) were understood earlier, while organometallic chemistry of the d- and f-block has ...
