A GENERAL-ROUTE TO SANDWICH AND HALF-SANDWICH TITANIUM IMIDO COMPLEXES - X-RAY STRUCTURE OF [TI(ETA(4)-ME(8)TAA)(NBU(T))] (ME(4)TAA=TETRAMETHYLDIBENZOTETRAAZA[14]ANNULENE) by Dunn, S, Batsanov, A, Mountford, P

“…The readily available complex [Ti(NBut)Cl2(Bu tpy)2] (Butpy = 4-tert-butylpyridine) is a useful precursor to a range of sandwich- and half-sandwich titanium imido derivatives including [Ti(η-C9H4Me3) (NBut)Cl(Butpy)] (C9H4Me3 = trimethylindenyl), [Ti(η-C5H5)2(NBu t)(Butpy)], [Ti(dmbpz)(NBut)Cl(Bu tpy)] [dmbpz = tris(3,5-dimethylpyrazolyl) borate] and [Ti(η4-Mentaa)(NBut)] {n = 4 or 8; Me (4 or 8)taa = (tetra- or octa-)methyl-dibenzotetraaza[14]annulene respectively}.…”

Monometallic and bimetallic titanium κ1‑amidinate complexes as olefin polymerization catalysts by Collins, R, Russell, A, Scott, R, Bernardo, R, van Doremaele, G, Berthoud, A, Mountford, P

“…Detailed olefin copolymerization studies for forming EPDM from ethylene, propylene, and certain dienes were carried out with mono- and bimetallic catalysts and borate and borane activators. Catalyst–activator effects on polymerization productivity and polymer composition relationships were mapped. …”
