Simple One-Pot Synthesis of Novel 5-(3,5-Dialkyl-1H-pyrazol-1-yl)-2-ethoxy-1,4,2λ5-diazaphosphole 2-Oxides

Simple One-Pot Synthesis of Novel 5-(3,5-Dialkyl-1H-pyrazol-1-yl)-2-ethoxy-1,4,2λ5-diazaphosphole 2-Oxides

A simple one-pot synthesis of novel 5-pyrazolyl-1,4,2-diazaphosphole derivatives is developed. The synthesis involves a three-component reaction of dimethyl (formamide/acetamide) dimethyl acetal or carbon disulfide with triethyl phosphite and 1 H -pyrazole-1-carboximidamides in dioxane. The structur...

Zusammenfassung:A simple one-pot synthesis of novel 5-pyrazolyl-1,4,2-diazaphosphole derivatives is developed. The synthesis involves a three-component reaction of dimethyl (formamide/acetamide) dimethyl acetal or carbon disulfide with triethyl phosphite and 1 H -pyrazole-1-carboximidamides in dioxane. The structure of the synthesized compounds was confirmed by spectral methods and elemental analysis.
