Zusammenfassung:	1,240,310. Cycloolefinic unsaturated alcohols. R. FIRMENICH, G. FlRMENICH, R. E. FIRMENICH and F. H. FIRMENICH, [trading as FIRMENICH & CIE.]. 7 Nov., 1968 [9 Nov., 1967; 1 Nov., 1968], No. 3392/71. Divided out of 1,240,309. Heading C2C. The invention comprises compounds of the general formulµ in which the dotted lines represent a double bond in either the 1- or 2-position in the ring. They may be prepared by reacting α- or (#-cyclocitral with an organometallic compound of formula ME-CH=CH-CH 3 or ME-C=C-CH 3 , in which ME is a metal function, e.g. Li- or BrMg-, and hydrolysing the product.
