Diastereoselective remote C-H activation by hydroboration

Hydroboration of tetrasubstituted or trisubstituted alkenes with BH 3 and subsequent thermolysis allows remote diastereoselective C-H activation of neighboring aryl rings. Tetrasubstituted and trisubstituted 1,1-diphenyl-ethylene derivatives undergo a highly stereoselective 1,2-rearrangement followed by remote C-H activation to lead, after oxidative workup, to a diol in which the relative stereochemistry of two stereocenters has been controlled. The mechanism of this remote activation has been studied and extended to related molecules that undergo this stereoselective C-H activation, namely alkenylbiphenyl systems or alkenes with only one phenyl ring, such as alkenylbenzenes. or bicyclic systems. We have shown that this reaction allows diastereoselective synthesis of molecules with up to three contiguous chiral centers.

Metallocene catalyst and preparing process of styrenic polymer using the same

Disclosed herein is a metallocene catalyst for use in the preparation of a styrenic polymer or copolymer. This metallocene catalyst contains a siloxy group introduced into an ancillary ligand bonded to a central metal of a transition metal compound. The introduction of the siloxy group is achieved by a reaction of the transition metal compound with a hydroxy functional group-containing silicone compound. The use of the metallocene catalyst of the present invention provides a styrenic polymer or copolymer having an excellent stereoregularity, a high melting point, and improved molecular weight and molecular weight distribution, even when it is used in combination with a small amount of a cocatalyst.
