Abstract
beta-Enehydrazino phosphonium salts 3 as well as beta-hydrazono phosph ine oxides 6 and phosphonates 7 are obtained from hydrazines, propargy lphosphonium sales 2 and phosphorylated allenes 4 and 5. beta-Function alized compounds 3,6 and 7 are used for the synthesis of a alpha,beta- unsaturated hydrazones 1, pyrazoline 14 and pyrazole derivative 15.
