Reaction Steps
In a suitable autoclave equipped as in Example 1, are added 200 parts of mono-n-hexylphosphine (93% purity) and 500 parts of isopropanol, as solvent. The mixture is heated to 60° C. and 240 parts of a 40% aqueous glyoxal solution are added. The reaction is allowed to proceed for one-hour and the solid product formed is filtered and dried to give 272 parts (98% yield) of 1,4-di-n-hexyl-2,3,5,6-tetrahydroxy-1,4-diphosphorinane, m.p. 140°-147° C.
