Praseodymium in the +5 oxidation state is a long-sought connection between lanthanide, early-transition and actinide metal redox chemistries. Unique among the lanthanide series, evidence for molecular pentavalent praseodymium species has been observed in
The synthesis of molecules that feature main-group elements in unusual oxidation states and coordination environments is a primary pursuit of main-group chemistry. The p-block elements saw early success towards this goal, and dozens of compounds that con
bicomponent excitation and promote the rapid charge transfer and separation to form the electron–hole pairs of BTTD•−and 9-AC•+under light illumination. The motifs in the excited state can quickly complete oxygen reduction to superoxide radical (O2•−) and C(sp3)–H bond activation...
The oxidation state of Fe in the brown ring complex [Fe(H2O5)NO]SO4 is 01:52 The IUPAC name of the complex [P(NH3)3Br(NO2)Cl]Cl is 04:05 A coordination complex compound of cobalt has molecular formula contai... 05:49 Which of the following contains maximum number of lone pairs ...
Volatile organic compounds (VOCs) are considered one of the significant contributors to air pollution because they are toxic, difficult to remove, come from a wide range of sources, and can easily cause damage to the environment and human health. There i

The active species for this epoxidation reaction is usually assumed to be titanium peroxo moieties, derived from four-coordinate titanium and peroxides. However, the isolation of the active intermediate remains a challenge owing to the inherent instability of such species. We have been able to ...
The chemistry of stable low oxidation state group 2 metal compounds was initiated in 2007 and has since expanded rapidly, yielding many surprises. Here the author outlines advances in the field and discusses some of the open questions and challenges that
