Abstract
The invention comprises glycols of the general formula <FORM:0908504/IV (b)/1> in which R1 represents an alkyl radical having not more than 6 carbon atoms or a cycloalkyl radical having from 3 to 8 carbon atoms, R2 and R3 represent alkyl radicals having not more than 4 carbon atoms, or R1 and R2 together may form an alkylene radical, and R4 represents an unsaturated aliphatic hydrocarbon radical having 2 or 3 carbon atoms. They may be prepared by reacting, preferably in an organic solvent, an a -hydroxy ketone of general formula <FORM:0908504/IV (b)/2> with an organometallic compound prepared from magnesium or zinc and a compound of formula Hal-CH2-R4, in which Hal represents chlorine, bromine, or iodine, followed by hydrolysis. If desired, compounds in which R4 contains a triple bond may be catalytically hydrogenated to reduce the triple bond to a double bond. The a -hydroxy ketones used as starting materials may be obtained from ketones of formula R1COR2 by converting them to the corresponding cyanohydrins, blocking the hydroxy group, e.g. by acylation, reacting the products with alkyl magnesium halides of formula R3MgHal and hydrolysing the products. Alternatively when R2 and R3 are both methyl groups the starting hydroxy ketones may be obtained by condensing ketones of formula R1COCH3 with alkali metal acetylides and adding water to the ethinyl methyl carbinols so obtained.
