A comprehensive overview on first row transition metal catalysts for C-H activation until summer 2018 is provided.Abstract:
C–H activation has surfaced as an increasingly powerful tool for molecular sciences, with notable applications to material sciences, crop protection, drug discovery, and pharmaceutical industries, among others. Despite major advances, the vast majority of these C–H functionalizations required precious 4d or 5d transition metal catalysts. Given the cost-effective and sustainable nature of earth-abundant first row transition metals, the development of less toxic, inexpensive 3d metal catalysts for C–H activation has gained considerable recent momentum as a significantly more environmentally-benign and economically-attractive alternative. Herein, we provide a comprehensive overview on first row transition metal catalysts for C–H activation until summer 2018.read more

A theoretical perspective of the agostic effect in early transition metal compounds
Xuhui Lin,Wei Wu,Yirong Mo +2 more
TL;DR: In this paper, the authors discussed the development of the agostic interaction concept in history and outlined the computational tools for characterizing the Agostic interaction in early-transition metal compounds, especially from the view of valence bond theory, and demonstrated that the nature of agostic effect is complicated and varies in different compounds.
