Suzuki coupling reaction has been often used for the preparation of a diverse set substituted pyrimidines. In this study, 2,4-dichloropyrimidines with aryl and heteroaryl boronic acids was investigated. A thorough screening conditions use microwave irradiation led to very efficient straightforward synthetic procedure providing C4-substituted pyrimidines in good excellent yields. Short time (15 ...

Ultrasound-assisted fermentation is a promising approach for improving food products’ nutritional and sensory qualities. This study compared the effects of ultrasound-assisted on chickpea-based beverages’ nutritive components. Proximate, phytochemical, microstructural data were examined to evaluate effectiveness processing techniques. The processed samples demonstrated significantly higher (p &...

The potential effects of three modern extraction technologies (cold-pressing, microwaves and subcritical fluids) on the recovery of oil from Chaenomelessinensis (Thouin) Koehne seeds have been evaluated and compared to those of conventional chemical extraction methods (Soxhlet extraction). This oil contains unsaturated fatty acids and polyphenols. Subcritical fluid extraction (SbFE) provided th...

Conversion of unsaturated fatty acids, FAMEs or triglycerides into the corresponding cyclic organic carbonates involves two reaction steps—double-bond epoxidation and CO2 insertion epoxide—that are generally conducted separately. We describe an assisted-tandem catalytic protocol able to carry out carbonation methyl oleate in one-pot without isolating epoxide intermediate. Methyl carbonate was o...

Microwave-assisted solid sampling analysis coupled to flame furnace atomic absorption spectrometry (MW-SS-FF-AAS) was used for Cd and Pb determination in food-contact polymer samples, with the aim of minimizing reagents laboratory waste. Operational parameters, such as FF tube design, oxygen flow rate, stoichiometry, sample mass, among others, were evaluated optimized. Calibration performed usi...
