摘要：Geometrical isomerization of cyclic epoxy alcohols such as cis- or trans-1,2-epoxy-3-hydroxycyclohexane may be equlibrated by the use of soluble transition metalcomplexes having the formula ##EQU1## WHEREIN L is a neutral ligand such as aphosphine, arsine, stibine, amine, olefin, diene, CO or the like, x is an integer of from 0-6but when x is 2 or more L may be the same or different; M is a Group VIII metal; n is aninteger of from 0-3 and denotes the valence state of the metal; X is an anionic ligand suchas hydrogen, chloride, bromide, iodide, lower alkyl, trichlorostanato, cyano or the like; y isan integer of from 0-3 which is equal to n but when y is 2 or 3, X may be the same ordifferent. When n is 0, then x equals at least 1, but when either x or y is 0, then the otherinteger must be at least 1.
