摘要

Abstract: Techniques for the preparation of a-lithio selenoxides have been developed. These reagents react cleanly with most aldehydes and ketones to give 0-hydroxy selenoxides, which can be thermolyzed to allyl alcohols or reduced to &hydroxy selenides, The P-hydroxy selenides are further transformed to olefins by reductive elimination. a-Lithio selenoxides can also be alkylated and acylated, although these reactions are of lesser ...
