Facile polyethylene glycol (PEG-400) promoted synthesis of β-ketosulfones
Suryakiran,Reddy, T. Srikanth,Ashalatha,Lakshman,Venkateswarlu
, p. 3853 - 3856 (2006)
An efficient and convenient synthesis of β-ketosulfones is described. Reaction of an α-haloketone with sodium alkyl/aryl sulphinate yields the corresponding β-ketosulfone promoted by polyethylene glycol (PEG-400) as an efficient reaction medium.
