Abstract Species that contain bonds between hydrogen and selenium or tellurium have a characteristic high reactivity, which can be harnessed in the synthesis of valuable organic compounds. This overview includes the synthesis of dihydrides, alkali metal hydrochalcogenides, chalcogenols, chalcogenocarboxylic and chalcogenocarbamic acids, and their application in reactions of reduction, addition to unsaturated compounds, and nucleophilic substitution.

In this work, we synthesized Prussian Blue (PB) by pyrolysis of nitrogen-rich organic compounds and ferric/ferrous salts in the presence of alkali metal salt in inert atmosphere at high temperature, which was completely different form popular method based on the reaction of ferric ions and ferrocyanide ions. By exploring the history of Prussian Blue and some research results, we proposed a possible mechanism to explain the formation of Prussian Blue. The mechanism is as follows: Firstly, carbon, nitrogen and oxygen element in the mixture were transformed to cyanate by the catalysis of alkali metal species. With the increasing of temperature, organic compounds decomposed to release reducing gases such as H<sub>2</sub> and CO and eventually formed carbon materials. The reducing gases reduced part of Fe<sup>3+</sup> to Fe<sup>2+</sup> and the carbon reduced the cyanate to cyanide. So Prussian Blue was formed by cyanide, Fe<sup>3+</sup> and Fe<sup>2+</sup>. The most import substance in the process is the alkali salts and a key intermediate product namely cyanate is proposed. Detailed experiments can be found in PDF file.

Abstract N-containing organic compounds are of vital importance to lives. Practical synthesis of valuable N-containing organic compounds directly from dinitrogen (N2), not through ammonia (NH3), is a holy-grail in chemistry and chemical industry. An essential step for this transformation is the functionalization of the activated N2 units/ligands to generate N−C bonds. Pioneering works of transition metal-mediated direct conversion of N2 into organic compounds via N−C bond formation at metal-dinitrogen [N2-M] complexes have generated diversified coordination modes and laid the foundation of understanding for the N−C bond formation mechanism. This review summarizes those major achievements and is organized by the coordination modes of the [N2-M] complexes (end-on, side-on, end-on-side-on, etc.) that are involved in the N−C bond formation steps, and each part is arranged in terms of reaction types (N-alkylation, N-acylation, cycloaddition, insertion, etc.) between [N2-M] complexes and carbon-based substrates. Additionally, earlier works on one-pot synthesis of organic compounds from N2 via ill-defined intermediates are also briefed. Although almost all of the syntheses of N-containing organic compounds via direct transformation of N2 so far in the literature are realized in homogeneous stoichiometric thermochemical reaction systems and are discussed here in detail, the sporadically reported syntheses involving photochemical, electrochemical, heterogeneous thermo-catalytic reactions, if any, are also mentioned. This review aims to provide readers with an in-depth understanding of the state-of-the-art and perspectives of future research particularly in direct catalytic and efficient conversion of N2 into N-containing organic compounds under mild conditions, and to stimulate more research efforts to tackle this long-standing and grand scientific challenge.
