Abstract: Title cpds. are of formula (I): (where R1 and R4 are Me or Et; R2 and R3 are H or Me; R5 is 1-6C alkyl or H; n is 1 or 2). They are obtd. by reacting alcohols of formula (II): with CO and H2 at 50-200 degrees C/100-1500 atmos, in the presence of carbonyl complexes of Gp. 7, and esp. rhodium carbonyl complexes e.g. 2 : 6 : 10-trimethyl-undeca-1:6-dien-10-ol is reacted with CO/H2 in a 1:1 ratio in the presence of dimeric cyclooctadiene-1:5-yl-rhodium chloride to give 3:7:11-trimethyl-dodeca-7-en-11-ol-1-al.
