Facile polyethylene glycol (PEG-400) promoted synthesis of β-ketosulfones
摘要:
An efficient and convenient synthesis of beta-ketosulfones is described. Reaction of an alpha-haloketone with sodium alkyl/aryl sulphinate yields the corresponding beta-ketosulfone promoted by polyethylene glycol (PEG-400) as an efficient reaction medium. (c) 2006 Elsevier Ltd. All rights reserved.

Synthesis of α-iodo β-ketosulfones and α-iodo methylsulfones using iodine monochloride
The synthesis of α-iodo β-ketosulfones and α-iodo methylsulfones is described. Reaction of β-ketosulfones with iodinemonochloride in aceticacid at room temperature gave the corresponding α-iodo β-ketosulfones, which, on treatment with aqueous alkali, underwent base-induced cleavage to afford α-iodo methylsulfones.
