Usage

General Description

3,4,5,6-Tetrachloropyridazine is a chemical compound with the molecular formula C4HCl4N2. It is a chlorinated derivative of pyridazine and is commonly used as a pesticide, herbicide, and fungicide. It is a crystalline, colorless solid that is sparingly soluble in water. 3,4,5,6-Tetrachloropyridazine is a potent and effective pesticide, acting as a neurotoxin in insects and pests. It is also used in the production of other chemical compounds and is known for its ability to effectively control a wide range of agricultural pests and pathogens. However, due to its toxic and persistent nature, it is important to handle and dispose of 3,4,5,6-Tetrachloropyridazine with caution to avoid environmental and human health risks.

Examination of Pyridazine as a Possible Scaffold for Nucleophilic Catalysis

Pyridazines with amino groups positioned para to each aromatic ring nitrogen and fixed in six-membered rings were prepared. The representative symmetric amino N-Et derivative was found to slightly exceed DMAP in catalytic activity in the acetylation reaction of a tertiary alcohol in C6D6. Nucleophilicity eclipsing that of DMAP was established in competitive reactions using phenacyl bromide as the electrophile, and the unsymmetric N-Et derivative was revealed to have even higher nucleophilicity.

Reaction of 4,5-dichloro-3-nitropyridazin-6-one with dimethylchloromethyleneammonium chloride

3,4,5-Trichloropyridazin-6-one, 3,4,5,6-tetrachloropyridazine and 4,5-dichloro-3-(N,N-dimethylamino)pyridazin-6-one were synthesized from 4,5-dichloro-3-nitropyridazin-6-one and dimethylchloromethyleneammonium chloride selectively.
