Summary: A new alkylation reaction of monosubstituted tetrazoles via the diazotization of aliphatic amines was reported in this study, allowing for preferential formation of 2,5-disubstituted tetrazoles. Additionally, a one-pot 1,3-dipolar cycloaddition/diazotization sequence starting from widely available nitriles was described. The quenching of azide residues with nitrite reagent in the second step limited the intrinsic risk associated with trimethylsilyl azide and the reaction conditions were compatible with several functional groups.

Summary: This study describes a method for the synthesis of disubstituted tetrazoles from 1H-5-monosubstituted tetrazoles via the aliphatic amine diazotization reaction. The transient alkyl diazonium intermediate acts as an alkylating agent. Although the 2,5-disubstituted tetrazole is preferentially formed, the minor 1,5-disubstituted tetrazole can also be isolated in some cases. The regioselectivities are highly variable and cannot be solely attributed to steric hindrance.

Summary: We investigated the effect of different organic coatings on the H-1-NMR relaxation properties of ultra-small iron-oxide-based magnetic nanoparticles. Magnetization measurements revealed similar behavior as a function of temperature and field for nanoparticles with different coatings but the same core diameter. However, the H-1-NMR longitudinal relaxivity showed different intensity and frequency behavior for the smallest particles depending on the kind of coating, indicating different electronic spin dynamics. On the other hand, no differences were found in the relaxivity of the biggest particles when the coating was changed.

Summary: This study investigated the reactions of CoFe2O4 magnetic nanoparticles supported ligands with cerium salts, and characterized the resulting nanocatalyst using various methods. The catalyst showed good activity and selectivity for the synthesis of 1H-tetrazoles and oxidation of sulfides under mild reaction conditions in a green medium. The immobilized complexes could be easily collected via an external magnetic field and reused multiple times without significant loss of catalytic activity and selectivity.

Summary: An efficient and sustainable synthetic protocol for the synthesis of 5-substituted 1H-tetrazole privileged heterocyclic substructures has been developed. The strategy involves a two-component reaction in water using L-lysine-palladium nanoparticles modified Fe3O4 nanoparticles as a magnetically separable, recyclable, and reusable catalyst, resulting in high yields of [2 + 3] cycloaddition with short reaction times. The use of water as a green solvent allows for a wide range of substrates to be utilized.
