일반 설명
4-Bromopyrazole is a heteroaryl halide and its cyanation in the presence of palladium catalysts has been reported.
4-Bromopyrazole is a pyrazole derivative. It is reported to react with titanium tetrachloride to afford binary adducts. Mutagenicity of 4-bromopyrazole has been tested using the L-arabinose forward mutation assay of Salmonella typhimurium. It is reported to inhibit the oxidative phosphorylation, the ATP-32P exchange reaction, and energy dependent and independent calcium uptake.
애플리케이션
4-Bromopyrazole may be used in the preparation of 4-bromo-1-(2-chloroethyl)-1H-pyrazole. It may be used as starting material in the synthesis of 1,4′-bipyrazoles.
4-Bromopyrazole may be used in the preparation of solid hexacoordinate complexes by reaction with dimethyl- and divinyl-tindichloride.
