procedure has been developed for the synthesis of dihydroxyacetonephosphate (DHAP). Reaction of 2,5-diethoxy-p-dioxane-2,5-dimethanol (1) and the trivalent phosphorylating reagent dibenzyl-N,N-diethylphosphoramidite (DDP) in the presence of 1,2,4-triazole or tetrazole followed by oxidation with H2O2 gave 2,5-diethoxy-p-dioxane-2,5-dimethanol-O-21-O-51- bis(phosphate) tetrabenzyl ester (2) in 98% yield

The reaction of N,N′-dialkyl-diphenylphosphinous amides (I) with alkyl benzenesulfonates (III) or dialkyl sulfates (IV) took place exothermally, giving phosphoniumsalts (V). When phosphoniumsalts (V) were heated at 100°C for 5–10 hr, asymmetricphosphine oxide (VI) and N,N′-dialkyl-benzenesulfonamides (VII) or polymeric materials were obtained. In the case of diphenyl dialkylphosphoramidites (II)

Reactions of 6-iodogalactosides with either methyl or isopropyl diphenyl phosphite lead to diphenylphosphoryl derivatives; these can be converted by ester exchange into dibenzylphosphoryl derivatives, which are convenient precursors of carbohydrate phosphonic acids.

The reaction of a trialkyl phosphite with trimethylsilyl iodide, which leads to O-trimethylsilyl esters of alkylphosphonic acid, has been shown to involve several steps, all of which are defined. The first step is the formation of the iodophosphite, involving a four centre mechanism in which PIII plays the role of electrophile. This is in contrast to the analogous reaction of phosphates with alkyl
