•The synthesized polystyrene supported salen type bis-thiopseudourea Pd(II) complex (3) was fully characterized.•This complex exhibited efficient catalytic activity in Suzuki cross coupling reactions.•The catalyst can be reused minimum 5 times with slight change in the activity.
A new salen type N′,N-1,2-phenylenebis(3-(4-fluorobenzoyl-2-benzyl-2-thiopseudourea) functionalized polystyrene resin supported palladium(II) complex (3) was found to be highly efficient catalyst for the Suzuki cross-coupling reaction of aryl halides with arylboronic acids. The coupled products of various activated and deactivated aryl halides were produced in good to excellent yields under low catalyst loadings and in water/methanol system. Further, the catalyst showed excellent recyclability without any significant loss in its activity.
