Procedure
In a suitable autoclave, equipped with mechanical stirring and external heating are added 200 parts of mono-isobutylphosphine (85%) and 300 parts of tetrahydrofuran, as solvent. With no external heating applied to the reactor, 275 parts of a 40% aqueous glyoxal solution are added with stirring at 20°-25° C. The resultant solid product is filtered, and dried to give 276 parts (97% yield) of 1,4-diisobutyl-2,3,5,6-tetrahydroxy-1,4-diphosphorinane, m.p. 173°-175° C.
