A new series of half-sandwich(borylcyclopentadienyl)titanium trichloride complexeshavebeen prepared which include the boryl substituents[1,2-(C6H4O2)]B-,Ph(Cl)B-, Ph2B- anda (PhB<)-bridged bimetallic complex. No correlation was foundbetween the 1H and 13CNMR chemical shifts of the cyclopentadienyl ring in these complexes andthe Lewis acidityof the attached boryl group. The crystal structure of thephenylboron-bridged bimetalliccomplexPhB{(
5-C5H4)TiCl3}2was determined. The cyclopentadienyltitanium units ofthemolecule are twisted away from each other, forming an angle of 41
between thecyclopentadienyl ring planes. Each cyclopentadienyl ring istwisted out of the trigonal planeof the boron by 24. Preliminary results concerning theTi-alkylation of some of thesecomplexes are described.
