This reaction demonstrates good yields of functionalized pyrazole derivatives with sodium methoxide, highlighting catalyst-free conditions.
Abstract The functionalized pyrazole derivatives produced from the reactions of hydrazonoyl chloride with ethyl 3-oxo-3-phenylpropanoate, acetylacetone, ethyl cyanoacetate, methyl cyanoacetate, or malononitrile in the presence of inexpensive sodium methoxide as base in DMF under catalyst-free condition in good yields.
