PdCl2 Immobilized in Polyacrylamide: a Low Cost and Eco
ABSTRACT. PdCl 2 immobilized in polyacrylamide (PAM), named Pd/PAM, produced at an extremely low cost, was found to be an efficient catalyst for Suzuki-Miyaura cross-coupling reactions. Iodo- and bromoarenes may couple with phenylboronic acid under eco-friendly conditions (i.e., phosphine-free and with ethanol as the solvent) to give excellent product yields.
Keywords: PdCl 2, polyacrylamide, Suzuki-Miyaura cross-coupling Introduction Suzuki-Miyaura cross-coupling is a versatile reaction in organic chemistry that is typically catalyzed by palladium salts with auxiliary ligands.1 Currently, among the most common catalysts for this reaction are PdCl 2 (PPh 3) 2, PdCl 2 L 2, and the mixture of Pd(OAc) 2

On the Use of Calcined Agro-Industrial Waste as Palladium
Abstract. Two calcined agro-industrial wastes [rice husk ash (RHA) and banana peel ash (BPA)] with immobilized PdCl 2 (Pd/RHA and Pd/BPA, respectively) that were produced at an extremely low cost were found to be efficient catalysts for Suzuki–Miyaura cross-coupling reactions. Iodo- and bromoarenes coupled with aryllboronic acid under eco-friendly conditions (i.e., phosphine-free and

Solid phase extraction using immobilized yeast
A solid phase extraction procedure using a yeast Saccharomyces cerevisiae immobilized in calcium alginate beads is proposed for the determination of Pd in road dust. Palladium was separated from the matrix elements by selective retention on the column at acidic pH (pH 1–1.5) followed by subsequent elution with 1 ml of thiourea (TU) solution (0.3 mol l −1 TU in 0.25 mol l −1 HC1) and

Handbook of organopalladium chemistry for organic
The development of organopalladium chemistry for organic synthesis has been even more sluggish than that of the organometallic chemistry of Mg and Li. It has been reported[6] that Wollaston in London discovered and isolated Pd in 1803 and named it after the asteroid Pallas, which was discovered a year before.

- Can polymeric iron sulphate be used for industrial effluent treatment?
- The combination of PFS with other chemicals or natural coagulants has high potential in treating water or wastewater. This is due to their greater effectiveness and cheaper cost compared to inorganic coagulants and organic flocculants . Previous studies of composite polymeric iron sulphate for different industrial effluent treatments
- What are Chemtrade's Fer+Ion® products?
- Chemtrade's Fer+Ion® products are custom blends of Ferric Sulphate formulated to help customers meet treatment goals. Chemtrade also works with customers to develop and supply special formulations of Ferric Sulphate with additives to address specific requests or provide a treatment benefit.
- Can Copperas be neutralised with sulphuric acid?
- Therefore, copperas will be partially neutralised with sulphuric acid under high concentration to form pre-hydrolysing coagulants with high molecular weight. Among them are poly-ferric sulphate (PFS; Figure 2b) [28, 29] and poly-ferric chloride which are frequently used to treat heavy metals in contaminated water or wastewater.
