    摘要： The present invention relates to a transition metal complex useful as a transition metal catalyst in the preparation of an ethylene homopolymer or a copolymer of ethylene and an α-olefin, a catalyst composition comprising the same and a process of preparing an ethylene homopolymer or a copolymer of ethylene and an α-olefin using the same. More particularly, it relates to a transition metal complex having a cyclopentadiene derivative and at least one phenyl oxide ligand substituted at the 2-position of phenyl with, for example, a silyl group having a C1-C30 hydrocarbon group or a C1-C20 hydrocarbon group, around a group IV transition metal, with no crosslinkage between the ligands, a catalyst composition comprising the transition metal complex and a cocatalyst selected from the group consisting of an aluminoxane and a boron compound, and a process for preparing an ethylene homopolymer or a copolymer of ethylene and an α-olefin using the same.

    摘要： The jineol extracted from scolopendra subspinipes is represented as the following formula (I): ##STR1## The jineol is obtained from scolopendra subspinipes by extracting scolopendra subspinipes with a solvent, separating an activating portion from the extracted liquid with an organic solvent, and purifying an anticancerous activating portion from the activating portion by chromatography. The jineol derivatives prepared from the jineol extracted scolopendra subspinipes are represented as the following formula (II): ##STR2## wherein each R.sub.1 and R.sub.2, independently of each other, is a hydrogen; a lower alkyl group of C.sub.1 to C.sub.6 ; a cycloalkyl group of C.sub.5 to C.sub.7 having a substituting group; an alkyl group of C.sub.1 to C.sub.4 having a phenyl group with one to three substituting groups; a lower alkyl group of C.sub.1 to C.sub.6 having a hydroxy, an alkoxy having C.sub.1 to C.sub.5, or an aryloxy; a lower acyl group of C.sub.1 to C.sub.7 having a hydroxy, an alkoxy having C.sub.1 to C.sub.5, or an aryloxy; a cycloalkylcarbonyl group of C.sub.5 to C.sub.7 with one to three substituting groups; or an acyl group of C.sub.1 to C.sub.4 having a phenyl group with one to three substituting groups.
