Diphenylphosphinodithioic acid is a reagent useful for a sequence effecting the hydrolysis of nitriles under mild conditions.

A new method was developed for converting nitriles into primary thioamides. Treatment of various nitriles 1 with 1.5-2.5 equivalents of sodium trimethylsilyl sulfide (sodium trimethylsilanethiolate) in 1,3-dimethyl-2-imidazolidinone at 20-35°C for 4-30 hours gave the corresponding thioamides 2 in 27-80% yield.

The crystal landscape of a series of primary aromatic thioamides is described, displaying similar characteristic intermolecular hydrogen-bonding interactions in the solid state to those observed in their widely studied amide analogues, including R22(8) dimers and C(4) chains. In a number of cases, high Z′ values were observed in the structures. On the basis of the observed solid-state features, the thioamide functional group, which is a strong hydrogen-bond donor and moderate acceptor, offers considerable potential as a key moiety for crystal engineering.

In this paper, a novel catalyst is introduced based on the immobilization of palladium on modified magnetic graphene oxide nanoparticles. The catalyst is characterized by several methods, including transmission electron microscopy, scanning electron microscopy, X-ray fluorescence, vibrating-sample magnetometer, Fourier transform-infrared and dynamic light scattering (DLS) analysis. The activity of the catalyst was investigated in the synthesis of 4(3H)-quinazolinones via Pd-catalyzed carbonylation-cyclization of N-(2-bromoaryl) benzimidamides by Mo (CO)6. The Mo (CO)6 is used as a carbon monoxide source for performing the reaction under mild conditions. The catalyst showed good reusability, and no change in activity was observed after 10?cycles of recovery.

Pyrazolecarboxamide fungicides are one of the most important classes of agricultural fungicides, which belong to succinodehydrogenase inhibitors (SDHIS). To discover new pyrazolecarboxamide analogues with broad spectrum and high activity, a class of new compounds of pyrazole carboxamide derivatives containing thiazole or oxazole ring were designed by scaffold hopping and bioisosterism, and 36 pyrazole carboxamide derivatives with antifungal activity were synthesized. Those compounds were evaluated against five phytopathogenic fungi, Gibberella zeae, Phytophythora capsici, Sclerotonia sclerotiorum, Erysiphe graminis and Puccinia sorghi. The results indicated that most of the compounds displayed good fungicidal activities, especially against E. graminis. Theoretical calculations were carried out at the B3LYP/6-31G (d, p) level and the full geometry optimization was carried out using the 6-31G (d, p) basis set, and the frontier orbital energy, atomic net charges, molecular docking were discussed, and the structure-activity relationships were also studied.
