Zinc (II) incorporated porous organic polymeric material (POPs): A mild and efficient catalyst for synthesis of dicoumarols and carboxylative cyclization of propargyl alcohols and CO2 in ambient conditions

Zinc (II) incorporated porous organic polymer catalyst, Zn@BBAPA has been designed, synthesized and characterized thoroughly by XRD, EDX, SEM, HR-TEM, FTIR spectra, UV–vis spectra, TGA and N2 absorption desorption isotherm. An eco-friendly porous Zn@BBAPA catalyst exhibits highly efficient catalytic performance for the production of α-alkylidene cyclic carbonates by using propargylic alcohols viaCO2 fixation.In addition the catalyst shows outstanding efficiency for the synthesis of various dicoumarol derivatives in green solvent medium (water)from 4-hydroxycoumarin and aromatic aldehydes. Presence of super hydrophobic nature and electron-donation characterof NH2 groups of BBA framework with high surface area is main aspect to be responsible for elevated catalytic performance as well as improvement in catalyst stability and enabling a good recyclability.
