Thiazoline functionalized periodic mesoporous organosilica (TPMO) supported palladium nanoparticles (Pd‐TPMO) were fabricated through a co‐condensation approach and successive incorporation of palladium nanoparticles using a double‐solvent technique. The TPMO and Pd‐TPMO were characterized through 29 Si MAS NMR, FTIR, SAXS, XPS, FESEM, TEM and N 2 adsorption‐desorption, which revealed the morphological and physicochemical properties of the materials. The catalytic performance of Pd‐TPMO was evaluated for hydrogenation of industrially important compounds and C sp 2 −C sp 2 bond‐formation reactions. The Pd‐TPMO mediated catalytic reactions were found to be effective in producing the corresponding products with excellent yields and selectivity. The size and stability of palladium nanoparticles within the confined organosilica framework promotes excellent activity and recyclability of the catalyst without a significant loss in the yields for hydrogenation and C sp 2 −C sp 2 bond‐formation reactions.
