Abstract
We have studied the reaction of 1,1-dichloro-2,2-difluoro-, chlorotrifluoro-, and tetrafluoro-ethylenes and also hexafluoropropylene withcis,trans andtrans,trans isomers of conjugated methyl octadecadienoate. Reactions gave 50-82% yields of cycloaddition products. The pre-ponderance of products with a cyclobutane struc-ture and a double bonda,β to the cyclobutane ring was shown by IR and NMR spectra.
Reactions were carried out in diluent with hy-droquinone inhibitor at autogenous pressure and a temperature of 200C for 5 hr. The distilled adducts are colorless liquids with viscosities rang-ing from 11 to 19 centistokes at 100F. These products and their hydrogenated derivatives ex-hibit low pour points (down to -76F) and may be useful as low-temperature plasticizers or lubricant additives.
