Zinc (II) incorporated porous organic polymer catalyst, Zn@BBAPA has been designed, synthesized and characterized thoroughly by XRD, EDX, SEM, HR-TEM, FUR spectra, UV-vis spectra, TGA and N-2 absorption desorption isotherm. An eco-friendly porous Zn@BBAPA catalyst exhibits highly efficient catalytic performance for the production of alpha-alkylidene cyclic carbonates by using propargylic alcohols via CO2 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 character of 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.
