Summary:
Di-(η5-cyclopentadienyl)dichlorotitanium(IV) reacts with salicylic acid or some of its ring-substituted derivatives in aqueous medium in the presence of alkali carbonate, giving (substituted) di-(η5-cyclopentadienyl)-salicylatotitanium(IV) complexes(3). Analogously, although less efficaciously, the dichlorotitanium compound reacts with phthalic acid to give the phthalato complex(5), and with dipicolinic acid to yield the pyridinedicarboxylato compound(7). Meticulous control of the experimental conditions is necessary to minimize hydrolytic side reactions. The product complexes(3) and(5) can be recrystallized from chloroform, in which they dissolve completely when freshly prepared; prolonged storage at ambient temperature causes reductions in solubility. I.r. and n.m.r. spectroscopic features of the product complexes are presented.
