Usage

General Description

Formaldehyde, also known as (3-methyl-2(3H)-benzothiazolylidene)hydrazone (9CI), is a chemical compound with the formula CH2O. It is a colorless, strong-smelling gas used in the production of resins, textiles, and various household products. It is also a common preservative and disinfectant. Exposure to formaldehyde can cause irritation to the eyes, nose, and throat, as well as more serious health effects such as respiratory issues and cancer. The (3-methyl-2(3H)-benzothiazolylidene)hydrazone (9CI) is a specific derivative of formaldehyde with potential uses in research and chemical synthesis. Both formaldehyde and (3-methyl-2(3H)-benzothiazolylidene)hydrazone (9CI) should be handled with care due to their potential health hazards.

Iminium Salts in Solid-State Syntheses Giving 100% Yield

Numerous reaction types in the field of iminium salts are performed in the gas-solid and solid-solid techniques in order to reach 100% yield. The stoichiometric runs are waste-free and do not require costly workup. Frequently, iminium salts were avoided, as acid catalysis was dispensable. Thioureas and α-halogenated ketones give a variety of 2-aminothiazoles via thiuronium salts in quantitative yield. A new intramolecular solid-state thermal condensation is reported. Enaminoketones are synthesized quantitatively from anilines and 1,3-diketones without catalysis and those can be used for quantitative solid-state 4-cascade reactions. Solid paraformaldehyde is used to produce methylene imines and internally trapped methylene iminium salts. Benzoylhydrazones are produced again without catalysis in the solid state. Vacuum and ball-mill techniques are particularly useful in the production of highly sensitive iminium salts. Hexahydro-1,3,5-triazines cyclorevert upon exposure to HCl gas to give solid arylmethylene iminium chlorides as new versatile reagents. These are used in arylaminomethylations of β-naphthol and of themselves to give Troeger's bases in 3-cascades. More direct are 4-cascade Troeger's base syntheses by dissolving hexahydro-1,3,5-triaryltriazines in trifluoroacetic acid. Alkylations of imines with trimethyloxonium tetrafluoroborate and triphenylmethyl cation give highly sensitive quaternary iminium salts in the ball-mill. The products are characterized by spectroscopic techniques and density functional theory (DFT) calculations at the B3LYP 6-31G* level. Molecular movements in the crystal and surface passivation are investigated with atomic force microscopy (AFM) techniques.
