alpha-Iodoketones are prepared in high yields from the initial reaction of various ketones with HNIB in CH3CN and subsequent treatment of potassium iodide or samarium(II) iodide.

A very convenient asymmetric synthesis of 1,2-diol monosulfonates and terminal epoxides with high optical purity via oxazaborolidine-catalyzedasymmetricboranereduction of α-sulfonyloxy ketones using N-ethyl-N-isopropylaniline–borane complex as borane carrier has been developed.
