ABSTRACT:
A process for producing homoallyl alcohols of the general formula (I) ##STR1## in which either A.sup.1 or A.sup.3 represents a hydrogen atom, the other represents a single bonding along with A.sup.2 ; R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are the same or different and independently represents a hydrogen atom, or an alkyl or alkenyl group with or without being substituted with a hydroxyl group or an akoxyl group; and Y represents a hydrogen atom, an alkyl group or an alkenyl group, by reacting 1,3-glycols of the general formula (II) ##STR2## in which X and Y are the same or different and independently represents a hydrogen atom, an alkyl group or an alkenyl group, R.sup.1, R.sup.2, R.sup.3, R.sup.4, and R.sup.5 independently represents as defined above, at a temperature in the range of 130.degree. to 250.degree. C. in liquid phase with the contact of .gamma.-alumina catalyst.
