In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis of pyrazole derivatives from 1,1-dimethylhydrazine and chlorovinyl ketones, published in 2001-12-31, which mentions a compound: 84547-64-8, mainly applied to chlorovinyl ketone cyclization methylhydrazine; pyrazol preparation; hydrazinium methyl chloride preparation, Category: amides-buliding-blocks.
The reaction of accessible 2-chlorovinyl Me ketones with 1,1-dimethylhydrazine gave pyrazole derivatives in high yields. 1,1,1-Trimethylhydrazinium chloride was isolated as second product of this reaction in high yield.
Here is just a brief introduction to this compound(84547-64-8)Category: amides-buliding-blocks, more information about the compound(3-(Chloromethyl)-1-methyl-1H-pyrazole) is in the article, you can click the link below.
