ABSTRACT:
Described is a process for preparing 2-phenyl-1,3-propanediol by converting the 2-nitro-2-phenyl-1,3-propanediol to a nitro-dioxane of the formula ##STR1## wherein the groups R are both C.sub.1 -C.sub.6 alkyl or together comprise a C.sub.5 -C.sub.6 cycloalkyl group, or wherein one R group is H and the other is phenyl; hydrogenolysis of the nitro-dioxane to give a dioxane of the formula ##STR2## wherein R is as defined above; and hydrolyzing the dioxane to form 2-phenyl-1,3-propanediol.
