The phase behaviour of the system poly(2,6-dimethyC1,4-phenyleneoxide) (PPO)antracene was investigated. An eutectic behaviour was deduced from calorimetric observations. In samples prepared by evaporation of a benzene solution, the melting point depression of both components and the eutectic melting
## Abstract Filicinic acid (5) was prepared in 75โ80% overall yield from 4,4โdimethylโ2โcyclohexenone (1). The key intermediate, tetrachlorodienone 2, underwent facile substitution of both ฮฒโchlorine substituents by methoxide affording the bis enol ether 3 which was converted into dichlorofilicinic
