Abstract: The invention comprises 13-(21,61,61-trimethyl-cyclohexene - (11) - y1 - (11)) - 3,7,11 - trimethyl-tridecahexene - (2,4,6,8,10,12) - oic-(1) and a process for the substitution of the carbonyl oxygen in the carbonyl group of an oxo compound by a radical of the formula which comprises reacting 5-(21,61,61-trimethyl-cyclohexene-(11) -y1-(11))-3 - methyl - pentadiene (1,4)-ol-(3), also known as vinyl-b -ionol and having the formula with triphenyl phosphine or a tri(alkyl substituted) phenyl phosphine and a proton donor or a hydrosalt of said triphenylphosphines and allowing the reaction to continue with an oxo compound by the action of a proton acceptor. As oxo compounds there may be used a formic acid ester of an aliphatic hydroxyl compound containing 1-8 carbon atoms or an aromatic hydroxy compound containing 6-8 carbon atoms, an aliphatic ketone or aliphatic aldehyde. An inorganic acid may be used as proton donor and an inorganic base as proton acceptor. In illustrative processes vinyl-b -ionol is reacted with 2,6-dimethyl-octatriene-2,4,6-al-(1)-oic-8 or an ester thereof with a hydroxy compound having 1 to 8 carbon atoms, or with 2,7-dimethyl-octatriene-(2,4,6)-dial-1,8 or 2,7-dimethyl-octadiene-2,6-ine-4-dial-(1,8). Specification 813,539 is referred to.

Abstract: Compounds bearing the cyclogeranylidene radical are obtained in a process which comprises reacting a compound of the general formula wherein n is 0, 1, 2, 3, or 4, and R is H or CH3 with a triarylphosphine by the action of a proton donor and continuing the reaction with an oxo compound by the action of a proton acceptor. A hydrosalt of a triarylphosphine may be used instead of the triarylphosphine and the proton donor. As proton donors there may be used strong inorganic acids, e.g. halogen hydracids and oxygen acids of sulphur and phosphorus which do not exert an oxidizing or reducing action under the reaction conditions. As proton acceptors acid binding agents such as organic bases, inorganic bases and organometallic compounds may be employed. Oxo-compounds are aliphatic and aromatic aldehydes and ketones and formic acid esters. Among the compounds mentioned as starting materials are: 2,6,6-trimethylcyclohexane-2-ylidene - 1 - methylene, 4 - (2,6,6 - trimethylcyclohexene - 21 - ylidene - 11) - butene - 2, 5 - (2,6,6 - trimethylcyclohexene - 21 - ylidene - 11)-3 - methylpentadiene - 1,3, 8 - (2,6,6 - trimethylcyclohexene - 21 - ylidene - 11) - 6 - methyloctatriene - 2,4,6, and 9 - (2,6,6 - trimethylcyclohexene - 21 - ylidene - 11) - 3,7 - dimethyl-nonatetraene-1,3,5,7. 4 - (2,6,6 - Trimethylcyclohexene - 21 - ylidene-11)-butene-2 is obtained by treating b -ionol with a dehydrating agent. The other hydrocarbon starting compounds are obtained in a similar manner from the corresponding alcohol. Specification 784,628 is referred to.
