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.

A series of triple chloro-bridged heterobimetallic phosphine complexes of the type [(PPh3)LClRuCl3RhClL2](L = PMe2Ph, PEt2Ph, PBun2Ph, PBun3, or PPh3) have been prepared from the mononuclear complexes [RuCl2(PPh3)3] and [RhCl3L3]; these reactions involve phosphine–ligand transfer from rhodium to ruthenium.

The conditions for the isolation of 1-phosphapropyne, CH3CP, recently detected by microwave spectroscopy in the products of the gas-phase pyrolysis of PEtCl2, have been studied by photoelectron spectroscopy. Although CH3CP is not the major product it can be trapped and separated from other reaction products under controlled conditions and subsequently revaporised. The He(I) photoelectron spectrum of CH3CP has been assigned and compared with that of FCP and HCP and the related nitrogen analogues.
