N′-Sulfonyl- and N′-Acylhydrazones of α- and β-Diphenylphosphorylalkanones: Synthesis and Structure

The interaction of saturated acyclic α- and β-(diphenylphosphoryl)alkanones with sulfonyl- and acylhydrazines has led to the corresponding hydrazones in yield up to 90%. Structure of the obtained compounds has been elucidated using the data of single-crystal X-ray diffraction analysis and NMR spectroscopy.
