Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 3-(Chloromethyl)-1-methyl-1H-pyrazole, is researched, Molecular C5H7ClN2, CAS is 84547-64-8, about 1-Alkylpyrazoles and 1-alkyl-5-chloropyrazoles from halovinyl ketones and 1,1-dialkylhydrazines.Application In Synthesis of 3-(Chloromethyl)-1-methyl-1H-pyrazole.
Regioselective heterocyclization of chlorovinyl ketones R1COCH:C(R2)Cl (R1 = Me, R2 = H; R1 = n-Pr, R2 = H, Cl; R1 = CH2Cl, R2 = H) with 1,1-dialkyl-hydrazines NH2N(R3)2 (R3 = Me, n-Bu) to pyrazoles I involved intermediate formation of the corresponding dialkylhydrazones II. The mass spectrum fragmentation pattern of chlorine-containing pyrazoles I (R1 = CH2Cl, R2 = H, R3 = Me; R1 = n-Pr, R2 = Cl, R3 = Me) depended on the position of the halogen atom.
