Optically active titanium complexes of the formula Ti(η5:η1−C5R4SiMe2NCHMePh)Cl2 (R = H, Me), containing the cyclopentadienyl ligand linked to a chiral 1-phenylethylamido moiety, were synthesized and characterized in both enantiomerically pure forms. A single-crystal X-ray structural analysis of (S)()Ti(η5:η1−C5H4SiMe2NCHMePh)Cl2 shows a conformation in which the phenyl group is turned away from the

The synthesis of alpha-oxazolinylalkanamides 2, based on the reaction of alpha-chloroalkyloxazolines 1 with hexacarbonyltungsten [W(CO)(6)] and lithium amides, has been developed. A plausible mechanism involving the ketene 5 as the intermediate is also proposed. (C) 2004 Elsevier Ltd. All rights reserved.
