摘要: The 1,3-dipolar cycloaddition reaction of the bis-hydrazonoyl chlorides with 2-arylidene-1-benzosuberone derivatives afforded corresponding bis-[1′,4′-diaryl-1-oxo-spiro-benzosuberane-2,5′-pyrazoline] derivatives. is carried out under ultrasonic irradiation as well conventional heating. factors affecting optimization are examined in detail. X-ray crystallographic analysis was used establishment regio- and stereochemistry products.
