Sugars phosphorus-containing reagents

The Preparation of Halodeoxy Sugars Using Phosphorus-Containing Reagents... 

Other examples of the use of phosphorus-containing reagents for the synthesis of deoxyhalogeno sugars, by way of Arbusov-type reactions, are described in Section 11,5 (see p. 278). 

A variety of phosphorus-containing reagents have been employed in sugar chemistry in the direct S,.,2 replacement of hydroxy groups mainly by halide ions [35]. Most of these reagents used a combination of triphenylphosphine with an electrophilic halogen source such as At-halosuccinimide [36,37], carbon tetrahalides [38-41], and more recently, tri-haloimidazole or iodine and imidazole [42-45] or related reagents [46J. The Mitsunobu...
