UN PROCEDIMIENTO PARA PREPARAR 6, 10, 14-TRIMETILPENTADECA-2-ONA.

摘要

6,10,14-Trimethylpentadecan-2-one (phytone) is prepared in high yield and high purity by (a) subjecting an olefin compound of the formula I below in which A denotes either the group <2bL>C=CH- or the group <2bL>CH-CH2- and X is either the group or the group to a hydroformylation reaction, (b) reacting the monoaldehyde formed in step (a) with acetone in the presence of a basic catalyst to give a hydroxyketone and eliminating water from the latter with the formation of an unsaturated ketone of the formula II below and (c) reducing the double bond(s) in the unsaturated ketone of the formula II to give a single bond, or single bonds.
