TRANSITION METAL COMPOUND AND METHOD FOR PRODUCING OLEFIN POLYMER

PROBLEM TO BE SOLVED: To provide a transition metal compound catalyst that makes it possible to synthesize an olefin polymer that is soft and has improved catalytic activity and reduced stereoregularity, and a method for producing an olefin polymer. SOLUTION: The present invention provides a compound represented by formula (IV) (X is a σ-binding or π-binding ligand; Y is a Lewis base; Y may be crosslinked to other Y and X; q is an integer of 1-5 and [(valence of M)-2]; r is an integer of 0-3; R1 and R2 independently represent H or halogen, alkyl or the like; R3-R10 are alkyl groups. M is metal elements of groups 3-10 or lanthanoid series in the periodic table; A1-A4 independently represent a crosslinking group composed of group 14 (C, Si, Ge, Sn)).

C-GLYCOSIDE DERIVATIVES AND SALTS THEREOF

The present invention provides C-glycoside derivatives and salts thereof, wherein B ring is bonded to A ring via -X- and A ring is directly bonded to the glucose residue, and it is usable as a Na+-glucose cotransporter inhibitor, especially for a therapeutic and/or preventive agent for diabetes such as insulin-dependent diabetes (type 1 diabetes) and insulin-independent diabetes (type 2 diabetes), as well as diabetes related diseases such as an insulin-resistant diseases and obesity.

Bridged metallocene complex for the (co) polymerization of olefins

A “bridged” bis-cyclopentadienyl complex which can be advantageously used for the formation of a catalytic system active in the (co)polymerization of ethylene and other a-olefins is represented by means of the following formula (II): wherein: M represents a metal selected from titanium, zirconium or hafnium; A′ and A″ each independently represent an anion containing an η5-cyclopentadienyl ring coordinated to M; or R″ each independently represents a group of an anionic nature a-bound to the metal M; B represents an unsaturated bivalent organic residue having from 1 to 30 carbon atoms bound, respectively, to the ring of group and to the -CH2- methylene group by means unsaturated carbon atoms. This complex, combined with a suitable cocata forms a catalyst with a high activity in the poization of olefins, producing polymers with molecular weight, especially in the case of the merization of ethylene with a second α-olefir.
