Nuclear magnetic resonance (NMR) spectra were measured on a Varian Mercury VX-300 NMR spectrometer operating at 300 MHz and run in deuterated dimethylsulfoxide (DMSO-d6). Chemical shifts were related to that of the solvent. Infrared (IR) spectra were measured on Shimadzu FTIR 8101 PC infrared spectrophotometers in KBr discs. Melting points were measured on an electrothermal IA 9000 series digital melting point apparatus. Elemental analyses were measured by using an Elementar Vario LIII CHNS analyzer. Mass spectra were recorded on a Shimadzu GCMS-QP1000 EX mass spectrometer at 70 eV.

Melting points were measured with an IA 9000-series digital melting-point apparatus (Bibby Sci. Lim. Stone, Staffordshire, UK). IR spectra were recorded in potassium bromide discs on FTIR 8101 PC infrared spectrophotometers (Shimadzu, Tokyo, Japan). NMR spectra were recorded on a Mercury VX-300 NMR spectrometer (Varian, Inc., Karlsruhe, Germany) operating at 300 MHz (1H-NMR) and run in deuterated dimethylsulfoxide (DMSO-d6). Chemical shifts were related to that of the solvent. Mass spectra were recorded on a Shimadzu GCeMS-QP1000 EX mass spectrometer (Tokyo, Japan) at 70 eV. Elemental analyses were measured using an ElementarVario LIII CHNS analyzer (elementar Analysensysteme GmbH, Hanau, Germany). Ultrasonication was carried out in an ElmaRD-7700 apparatus (Singen, Germany). The electric supply was 230 V, A.C. 50 Hz, 1 phase; the ultrasonic frequency was 36 KHz and the ultrasonic power 100 W. 1,4-Dioxo-3,4-dihydrophthalazine-2(1H)-carbothioamide (1) [36 (link)] and hydrazonoyl halides 2 and 5 [37 (link)] were prepared as previously reported in the respective literature.

Melting points were measured on an Electrothermal IA 9000 series digital melting point apparatus (Bibby Sci. Lim., Stone, UK). IR spectra were recorded in potassium bromide discs on PyeUnicam SP 3300 and Shimadzu FTIR 8101 PC infrared spectrophotometers (Shimadzu, Tokyo, Japan). NMR spectra were measured on a Varian Mercury VX-300 NMR spectrometer (Varian, Inc., Karlsruhe, Germany). 1H spectra were recorded at 300 MHz and 13C spectra were recorded at 75.46 MHz in deuterated dimethyl sulfoxide (DMSO-d6). Mass spectra were run on a Shimadzu GCMS-QP1000 EX mass spectrometer (Tokyo, Japan) at 70 eV. Elemental analyses were measured using a German-made Elementarvario LIII CHNS analyzer. Biological activities of the synthesized compounds were carried out at the Regional Center for Mycology and Biotechnology at Al-Azhar University, Cairo, Egypt.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
