Participants

Reaction Steps

0.2 g. of 4,8-dimethyl-10-(4-oxo-2,6,6-trimethyl-2-cyclohexenylidene)-2,4,6,8-decatetraenal and 0.35 g. of 2,6-dimethyl-8-(4-oxo-2,6,6-trimethyl-2-cyclohexenylidene)-2,4,6-octatrien triphenylphosphonium bromide were dissolved in 6 ml. of methanol and treated with 0.2 g. of sodium methoxide at 0° for 4 hours.
