摘要：
There are provided novel triene hydrocarbons, having at least two conjugated double bonds, and being of the general formula IN WHICH A is a radical consisting of a ring containing an endomethylene group; B may be both a linear alkadiene radical and a substituted and unsubstituted alkene or cycloalkene radical; Ro may be hydrogen, an aryl or an alkyl radical, n is a number ranging from 0 to 3; and m is 0 or 1. If n is not 0, m is 0; if n is 0, m is 0 or 1.
