Graphene oxide grafted with Pd17Se15 nano-particles generated from a single source precursor as a recyclable and efficient catalyst for C–O coupling in O-arylation at room temperature

The Pd17Se15 nanoparticles, synthesized for the first time from a single source precursor [Pd(L)Cl2] {L = 1,3-bis(phenylselenyl)propan-2-ol} and grafted onto graphene oxide, show high catalytic activity in C-O coupling between aryl/heteroaryl chlorides/bromides and phenol at room temperature (Pd loading 1 mol%; yield up to 94%).

Single source precursor routes for synthesis of PdTe nanorods and particles: solvent dependent control of shapes

The PdTe NPs (hexagonal) and nanorods (first example) have been synthesized for the first time from single source precursors (SSPs), [Pd(L1)Cl2] (1) and [Pd(L2)Cl]BF4 (2) [L1, 4-bromo-1-[2-(4-methoxyphenyltellanyl)ethyl]-1H-pyrazole; L2, bis-[2-(4-bromopyrazol-1-yl)ethyl]telluride], by their thermolysis in an OA–ODE mixture (1:1) and TOP respectively. The composition of the PdTe phase does not change with SSP/solvent. Complex 2 gives small size nanostructures.
