catalyst, which was thoroughly characterized by means of EDS, SEM, TEM, XRD, XPS, and FT‐IR, revealed excellent catalytic activity for the reaction of diphenyl phosphinamide with benzylalcohols through borrowinghydrogenstrategy and acceptorless dehydrogenation with wide functional group tolerance. Moreover, this POP−Ir catalyst could be simply recovered and reused for at least five times without a significant
comparable to the IC50 of cisplatin reference. Moreover, the potential use of the calcium citrate nanoparticles (CaCit NPs) as a platform for drug delivery system was studied on a selected 1,3,5-triazinederivative 2a. Condition optimisation revealed that the source of citrate ions and reaction time significantly influence the morphology, size and %drug loading of the particles. With the optimised conditions

An efficient copper(II) catalyzed iodine-promoted synthesis of aroylimidazo[1,2-a][1,3,5]triazines from 2-amino-1,3,5-triazines and chalcones under mild conditions has been developed. The reaction occurred with good yields and excellent regioselectivities, and tolerated chalcone containing functionalities such as ethers, halogens, and nitro groups. The successful application of this methodology for
