Abstract:

Titanocenos são catalisadores solúveis conhecidos para a polimerisação estereoespecífica de olefinas pró-quirais como o estireno. Nesse trabalho descrevemos as relações entre as características do poliestireno e a estrutura do precursor do catalisador, de fato aqueles da família (RCp)2TiCl2 (R = H, etila, iso-propila, n-propila, sec-butila, n-butila, iso-amila e ciclohexila). Todos os catalisadores são ativos para a produção de poliestireno acima de zero graus centígrados. A sindiotaticidade dos polímeros são dependentes da cadeia lateral dos anéis aromáticos do titanoceno e da temperatura da

Uma série de sete complexos alquil substituídos do tipo (RCp)2TiCl2 (R= H, etila, n-propila, iso-propila, n-butila, iso-amila, ciclo-hexila) foi preparada juntamente com o ainda inédito contendo R= sec-butila, e o efeito do substituinte na polimerização do estireno foi investigada à temperaturas de polimerização de 0 e 50 ºC. Foi encontrado que R = n-butila maximiza a produção de poliestireno sindiotático. Ligantes alquilas com R = RCH2- são superiores aos R = RR’CH- e ao precursor Cp2TiCl2 na produção de poliestireno sindiotático de alto peso molecular.

Abstract:

An operationally simple, convenient, and mild strategy for the synthesis of triazole-substituted titanocenes via strain-driven 1,3-dipolar cycloadditions between azide-functionalized titanocenes and cyclooctyne has been developed. It features the first synthesis of titanocenes containing azide groups. These compounds constitute ‘second-generation’ functionalized titanocene building blocks for further synthetic elaboration. Our synthesis is modular and large numbers of the complexes can in principle be prepared in short periods of time. Some of the triazole-substituted titanocenes display high

Abstract:

Abstract Acute lymphoblastic leukemia (ALL) is the most common malignant disease in childhood. Despite a relatively good prognosis approximately one fourth of the patients suffers from relapse and, consequently, a worse prognosis. Only 40% of these children with relapsed ALL will survive. Patients who fail to achieve a complete remission in chemotherapy do not survive. This explains the need for new compounds that may overcome resistance against clinically employed cytostatic drugs. In the present study we examined novel titan-containing agents concerning their cytotoxic potential with great s

The functionalization of titanocene dichloride with amides enhances the cytotoxic activity in MCF-7. Two sets of titanocenyl amides can be identified, with IC50<100 μM and IC50>100 μM.

Abstract:

The opening of epoxides typically requires electrophilic activation, and subsequent nucleophilic (SN2) attack on the less substituted carbon leads to alcohols with Markovnikov regioselectivity. We describe a cooperative catalysis approach to anti-Markovnikov alcohols by combining titanocene-catalyzed epoxide opening with chromium-catalyzed hydrogen activation and radical reduction. The titanocene enforces the anti-Markovnikov regioselectivity by forming the more highly substituted radical. The chromium catalyst sequentially transfers a hydrogen atom, proton, and electron from molecular hydroge
