Abstract: Title cpds of formula (I): (where R is H, 1-5C aliphatic hydrocarbon or mono-nuclear aryl) are prepd by reacting isoprene with a prim alcohol RCH2OH over a PD(II) catalyst contg in addn a tert phosphine and/or phosphite and/or arsine (II) and a base strong enough for the reaction mixt to be alcoholation free, the molar ratio (II):Pd being 0.5:1-4.1. (I) are perfumes with a fruity note and inters for terpenes. They are used in the prodn of resins, detergents, and polymers. Only small amts of the 2,7-dimethyl-2,6-octadienyl ether are obtd as by prodt. and are readily sepd. from (I) by fractionation.

Abstract: Title cpds are of formula: A-C=CH-CH2-CH2-C=CH-CH2-CH2-C-CH=CH2 (in which A is or where R1 and R2 are aliphatic 1-8C hydrocarbon gps. or form together a 2-8C alkylene or a cycloalkylene gp. contg. 5 or 6 C atoms in the ring, or o-phenylene gp). The cpds. have tangerine or orange aroma. From the acetals, valuable natural orange aroma materials, ie. alpha- and beta-sinensals, can be easily produced by dehydration and acid hydrolysis.
