Abstract:
1. A process for producing a 2,2,4,4-tetraalkylcyclobutane-1,3-diol of Formula II, comprising contacting a 2,2,4,4-tetraalkylcyclobutane-1,3-dione with hydrogen in the presence of a ruthenium-promoted cobalt-based catalyst under conditions of temperature and pressure sufficient to form a 2,2,4,4-tetraalkylcyclobutane-1,3-diol, wherein each of the alkyl radicals R 1 , R 2 , R 3 and R 4 has independently from 1 to 8 carbon atoms and wherein the ruthenium-promoted cobalt-based catalyst comprises an alumina support.
