In a novel method, the reaction of hydroxylamine hydrochloride with a number of aldehydes and ketones under microwave irradiation and solventless ‘dry’ condition gave oximes in excellent yield.
4,4′-Oxydiphthalic anhydride (1) was reacted with L-leucine (2) in acetic acid, and the resulting imide-acid (3) was obtained in high yield. The diacid chloride (4) was obtained from diacid derivative (3) by reaction with thionyl chloride.
A new polymeric sorbent prepared by utilizing molecular imprinting technology was used for the selective extraction of hydrochlorothiazide (HCT) from pharmaceutical and human serum sample.
Various N-bromo reagents [HMTAB, DABCO-bromine, DPTBE, and TBCA] were used as effective oxidizing agents for the
In recent years, polyimide (PI) hybrid materials have received considerable attention owing to the dramatic enhancements over their pristine state in thermal stabilities, mechanical properties and other special features by introducing only a small fraction of inorg
The utilization of microwave energy in polymer synthesis is a fast growing field of research leading to a more rapid and cleaner polymerization process.
