The hydride <b>3</b> is a catalyst that effects the regio- and stereoselective homodimerization of a range of α-olefins at 80 °C as well as head-to-head codimerization of styrene with other α-olefins. 1998-01-16 00:00:00 stereoselective homodimerization olefins YCH Regioselective Homo hydride 3 Ind
