Photocatalyst Ir[dF(CF3)ppy]2(dtbbpy)PF6 (4.5 mg, 2 mol%), aromatic carboxylic acid (0.2 mmol, 1.0 equiv), aryl bromide (0.4 mmol, 2.0 equiv), Ph3P (78.6 mg, 0.3 mmol, 1.5 equiv), anhydrous powder K3PO4 (42.4 mg, 0.2 mmol, 1.0 equiv), and anhydrous...
carboxylic acid derivatives chapter. But for right now, all I'm trying to say is that acid chlorides and esters when reacted with organometallics are going to react twice instead of reacting once. Let's take a look. First of all, remember that organometallics have a...

A bispallacycle catalyst contributed to the first palladium catalysts capable of controlling asymmetric nucleophilic allylations of aldehydes with allyltributyltin, with superior catalytic activity. Known from IR studies, the binding of the aldehyde is much more efficient with thebimetallic catalyst(Scheme...
IR (KBr, cm À1): 1670 (C ¼ O, stretching), 2500–3000 (O–H, vibration, broadband). Synthesis of hyperbranched poly(ether ketone) with carboxylic acid terminal group (P2) In a 5-ml flask, 0.3 g of monomer 1 was mixed with 2 ml of PPMA.39,40 The reaction mixture was ...

The structure of the sulphonated copolymer was identified from FT-IR and H-1-NMR spectrum. The pendant carboxylic groups of SPEEK-C were further crosslinked with poly(vinyl alcohol) (PVA) to fabricate the crosslinked (SPEEK/PVA) membranes. The performance of the membranes was evaluated in ...
