Ep. Serebryakov et al., (eta(6)-Naphthalene)tricarbonylchromium-mediated hydrogenation of 3,5-diene-1,7-diynes as a route to (Z,Z,Z)-1,4,7-trienes, MENDELEEV C, (5), 2000, pp. 168-169
The hydrogenation of internal 3,5-diene-1,7-diynes over (eta (6)-naphthalen
e)tricarbonylchromium affords homoconjugated (Z,Z,Z)-1,4,7-trienes as major
products.
