摘要：

A new series of half-sandwich (borylcyclopentadienyl)titanium trichloride complexes have been prepared which include the boryl substituents [1,2-(C6H4O2)]B-, Ph(Cl)B-, Ph(2)B- and a (PhB<)-bridged bimetallic complex. No correlation was found between the H-1 and C-13 NMR chemical shifts of the cyclopentadienyl ring in these complexes and the Lewis acidity of the attached boryl group. The crystal structure of the phenylboron-bridged bimetallic complex PhB{(eta(5)-C5H4)TiCl3}(2) was determined. The cyclopentadienyltitanium units of the molecule are twisted away from each other, forming an angle of 41 degrees between the cyclopentadienyl ring planes. Each cyclopentadienyl ring is twisted out of the trigonal plane of the boron by 24 degrees. Preliminary results concerning the Ti-alkylation of some of these complexes are described.
