Claim 5
Dependent Claim
230 words
A method of preparing the new compounds of claim 1, which method comprises: reacting (a) an acyclic triene compound containing a total of eight carbon atoms per molecule, from seven to eight carbon atoms in the linear portion of said molecule, and at least one terminal carbon to carbon double bond in said linear portion, with (b) a halocyclopentadiene having the formula wherein A and B are as defined in claim 1, to obtain a monoadduct characterized by the presence of a radical attached to the carbon atoms in the 1 and 2 positions in the linear portion of said triene molecule, and wherein A and B are as defined in claim 1; a carbon to carbon double bond between the carbon atoms in the 3 and 4 positions in the linear portion of said triene molecule; and another carbon to carbon double bond between the carbon atoms in the 5 and 6, the 6 and 7, or the 7 and 8 positions where the linear portion of said triene molecule contains eight carbon atoms; and then reacting said monoadduct with bromine at a temperature within the range of about -40* C. to about 70* C. and in the presence of an inert diluent so as to add two atoms of bromine to said monoadduct in said 5 and 6, said 6 and 7, or said 7 and 8 positions.
