The effect of ethylene pressure on the copolymerization of ethylene with 1hexene was studied. The results show an increasing of productivities (g of polymer/ n Zr h) with pressure. This tendency was not observed for the activity (g of polymer/ n Zr h bar) that decreases when pressure is raised. When

The asymmetric ene reaction of N-glyoxyloyl-(2R)-bomane-10,2-sultam 2 and its hemiacetal 3 with 1-pentene 4 and 1-hexene 5 in the presence of Lewis acids is reported. All the ene reactions studied led to diastereoisomeric mixtures of olefins 6 and 7 or 8 and 9, with predominance of products of the (
The kinetics of the reactions of ground state oxygen atoms with 1-pentene, 1-hexene, cis-2pentene, and trans-2-pentene was investigated in the temperature range 200 to 370 K. In this range the temperature dependences of the rate constants can be represented by k Ο AΠ T n exp(Οͺ E a Π/RT) with AΠ Ο (1
