Microwave-Assisted Synthesis of MOCHAs

Check if the same lab product or an alternative is used in the 5 most similar protocols

MOCHAs were fabricated in an Anton Parr Monowave 300 Microwave Synthesis Reactor. 0.5 mmol AgNO₃ (abcr, 99.9%) were dissolved in 2 mL H₂O. 0.75 mmol of the diphenyl dichalcogenide (DPDS, DPDSe) (Acros Organics, 99%) were dissolved in 5 mL methanol by sonicating the suspension for 45 min in an ultrasonic bath. These two solutions were combined in the microwave vial which was closed and heat by microwave irradiation at 110 °C for 5 h under continuous stirring at 600 rpm. The obtained MOCHA was rinsed and washed with methanol by vacuum filtration and stored in a drying oven at 40 °C for 24 h.

Compounds not described in ESI were purchased from commercial vendors. All synthesized compounds were characterized with the following instrumentation: Varian Unity-Inova 400 MHz NMR spectrometer (operating at 400 and 101 MHz, respectively) or a Varian Unity-Inova 500 MHz NMR spectrometer (operating at 500 and 126 MHz, respectively) in CDCl₃ (CDCl₃: ¹H = δ 7.26 ppm, ¹³C = δ 77.16 ppm). Microwave irradiated (MWI) reactions were carried out using an Anton Paar Monowave 300 Microwave Synthesis Reactor. Flash chromatography separations were carried out using a Teledyne Isco CombiFlash Rf 200 purification system with silica gel columns (normal-phase). High resolution mass spectra (HRMS) were performed by Analytical Instrument Center at the School of Pharmacy on an Electron Spray Injection (ESI) mass spectrometer. Melting points were measured on OptiMelt MPA100 Automated Melting Point System.

Quaternized Chitosan Derivatives by Microwave

Check if the same lab product or an alternative is used in the 5 most similar protocols

GTMAC was grafted on chitosan under microwave
irradiation^{33 (link)} to form a quaternized derivative
of chitosan referred to as QCh8 (8 equiv of GTMAC per monomer unit),
QCh6 (6 equiv of GTMAC per monomer unit), and QCh3 (3 equiv of GTMAC
per monomer unit). To this end, 0.15 g of chitosan was dispersed in
10 mL of distilled water and 50 μL of glacial acetic acid under
constant stirring (500 rpm) at room temperature for 10 min. Afterward,
1000 μL (QCh8), 750 μL (QCh6), or 370 μL (QCh3)
of GTMAC was added dropwise and the mixture was subjected to microwave
irradiation at a constant temperature of 85 °C (by adjusting
the applied power after a fast initial heating) for 30 min under constant
stirring using a monowave 300 microwave synthesis reactor from Anton
Paar. After cooling, the reaction medium was poured in ethanol to
dissolve residual GTMAC. Then, the product was precipitated by the
addition of acetone (ethanol/acetone with v/v 1:3). It was filtered
on sintered glass, intensively rinsed with acetone, and dried at 40
°C for 24 h.

Microwave-assisted reactions were carried out in an Anton Paar Monowave 300 Microwave Synthesis Reactor (Anton Paar GmbH, Graz, Austria) in 10 mL sealed vials. To run a microwave experiment the same quantities of solvent, pesticide, and piperidine as kinetic measurements were used. Measurements were carried out at 50°C and 500 rpm, each measurement was made in triplicate. To evaluate the % of degradation of the pesticide the reaction mixture was analyzed by ³¹P NMR.

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.
