Bj. Deelman et al., ORGANOLANTHANIDE-CATALYZED OLIGOMERIZATION OF 2-CYCLOALKEN-1-ONES, Journal of the Chemical Society, Chemical Communications, (17), 1995, pp. 1741-1742
Yttrium and lanthanum hydrides [(C(5)Me(5))(2)LnH](2) are active catal
ysts for the oligomerisation of 2-cycloalken-1-ones; the average degre
e of oligomerisation increases with temperature.
