4- Ethyl-l-hexene

Account for the fact that addition of CBrC in the presence of peroxides takes place faster to 2-ethyl-l-hexene than to 1-octene. 

Similar unsatisfactory results, usually with even lower inductions are obtained with other terminal aliphatic alkenes such as 1-pentene, 2-methy]-l -butene, 3-methyl-l -butene, 2,3-dimethyl-l-butene, 3,3-dimethyl-l-butene, 2,3,3-trimethyl-l-butene, 2-ethyl-l-hexene, I-hex-ene and 1-octene (Table 1).

As shown in Scheme 1.30, the chiral titanocene catalyst 34 hydrogenates unfimctionalized, disubstituted styrenes under 136 atm of hydrogen at 65°C to give the saturation products with 83 to >99% ee [156]. A high enantioselectivity is now realized only with aiyl-substituted olefins. The enantioselectivity of 41% ee attained 2-ethyl-l-hexene and 34 as catalyst is the highest for hydrogenation of non-arwnatic olefins.
