Reactions of ionic or covalent azides with chalcogen halides or, in the case of sulfur, with the elemental chalcogen provide an alternative route to certain chalcogen-nitrogen compounds. Eor example, the reaction of sodium azide with cyclo-Sa in hexamethylphosphoric triamide is a more convenient synthesis of S7NH than the S2CI2 reaction (Section 6.2.1). Moreover, the azide route can be used for the preparation of 50% N-enriched S7NH. 

Electrochemical methods may also be used in the synthesis of chalcogen-nitrogen compounds. For example, the electrochemical reduction of salts of the [SsNs]" cation (Section 5.3.9) in SO2 or CH2CI2 at low temperatures produces microcrystals of the superconducting polymer (SN). ... 

The reaction of A-acyliminium ions with nucleophilic carbon atoms (also called cationic x-amidoalkylation) is a highly useful method for the synthesis of both nitrogen heterocycles and open-chain nitrogen compounds. A variety of carbon nucleophiles can be used, such as aromatic compounds, alkcncs, alkyncs, carbcnoids, and carbanions derived from active methylene compounds and organometallics. 

Many microorganisms can synthesise amino acids from inorganic nitrogen compounds. The rate and amount of some amino acids may exceed the cells need for protein synthesis, where the excess amino acids are excreted into the media. Some microorganisms are capable of producing certain amino acids such as lysine, glutamic acid and tryptophan.

Nitrous acid or alkyl nitrites react with a number of nitrogen compounds to yield tetrazoles. For example, hydrazidines (87), which can be prepared in situ from the corresponding iminoesters, react with nitrous acid or its derivatives to give 1-substituted tetrazoles (88).150-152 This reaction (Eq. 17), is one of the most extensively used methods for the synthesis of... 

Nitrogen compounds are also effective as nucleophiles in the anodic oxidation of silyl-substituted ethers. The electrochemical oxidation in the presence of a carbamate or a sulfonamide in dry THF or dichloromethane results in the selective cleavage of the C-Si bond and the introduction of the nitrogen nucleophile at the carbon (Scheme 21) [55]. Since a-methoxycarbamates are useful intermediates in the synthesis of nitrogen-containing compounds [44], this reaction provides useful access to such compounds. Cyclic silyl-substkuted ethers such as 2-silyltetrahydrofurans are also effective for the introduction of nitrogen nucleophiles. The anodic oxidation in the presence of a carbamate or a... 

Nitrogen Compounds.—The formation of ZrNj 9 by a new method of evaporation synthesis has been described. The compound LiZrN2 has been prepared from LijN and ZrNi 22 and X-ray crystallographic studies have shown that the crystals contain hexagonally close-packed nitride ions, with Zr" and Li ions in octahedral and tetrahedral holes, respectively. ...
