Cydohexadienes hexatrienes

Products. Photolysis of 1,3-cyclohexadiene gives rise to 1,3,5-hexatriene of unknown stereochemistry. During irradiation in the condensed phase

initial product is the m-triene which subsequently isomerizes photochemically. The other primary processes which seem to originate directly in 1,3-cydohexadiene are dehydrogenation ... [Pg.130]

The limited range of conjugated dienes that can be anionically polymerized is shown in Scheme 2. There has been renewed interest in the anionic polymerization of 1,3-cydohexadiene, even though chain transfer and chain termination reactions can occur. " 1,3,5-Tiienes such as tram-1,3,5-hexatriene can be polymerized by alkyUithium-initiated anionic polymerization, but it was not possible to eliminate branching reactions. Monoaddition to poly(styryl)lithium (PSIi) was effeaed by the addition of 1.2 equivalents of tram-1,3,5-hexatriene at -10 °C... [Pg.561]
