The civilian, commercial, and defense sectors of most advanced industrialized nations are faced with a tremendous set of environmental problems related to the remediation of hazardous wastes, contaminated groundwaters, and the control of toxic air contaminants. For example, the slow pace of hazardous waste remediation at military installations around the world is causing a serious delay in conversion of many of these facilities to civilian uses. Over the last 10 years problems related to hazardous waste remediation have emerged as a high national and international priority.

Environmental Applications of Semiconductor Photocatalysis

The Cationminus signpi Interaction.

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.

Free Radical Lipid Peroxidation: Mechanisms and Analysis

Catalytic activities of Schiff base transition metal complexes

The first examples of isomerisation of 1,1-dimethyl-π-allyl metal complexes to the corresponding 1,2-dimethyl-π-allyl compounds are described.

New type of π-allyl isomerisation: conversion of 1,1-into 1,2-dimethylallyl complexes of cobalt and rhodium

UV photoelectron spectra of [RH2X2L4], (X = Cl, Br, I), (L = CO, PF3) and Ir2Cl2(PF3)4

Phospha-alkenes X–PCTMS2(X = F, Cl, l; TMS = SiMe3) display different reaction behaviour towards metal complexes (Bu3P)2Ni(cod)(cod = cyclo-octa-1,5-diene) or (Ph3P)2Pt(C2H4), respectively, undergoing either co-ordination to give η2;phospha-alkene complexes or alternatively oxidative addition of the P–X bond, forming phospha-alkenyl-metal(II) complexes, [(R3P)2M(X)(σ-PCTMS2)].
