Nucleophilic additions on 2,2´-bipyridine and 1,10-phenantroline ligands in rhenium tricarbonyl complexes

Nucleophilic additions on 2,2´-bipyridine and 1,10-phenantroline ligands in rhenium tricarbonyl complexes

Abstract

Los ligandos 2,2’-bipiridina (bipy) y 1,10-fenantrolina (phen) han sido considerados inertes frente a nucleófilos en complejos de metales de transición. Como consecuencia, las reacciones de formación de enlaces en ligandos bipy o phen son inusuales. En la presente memoria se describen por primera vez adiciones nucleofílicas intramoleculares (iniciadas por la desprotonación de los grupos metilo de un co-ligando) e intermoleculares a ligandos bipy y phen en complejos tricarbonílicos de renio. Se han caracterizado los nuevos compuestos mediante espectroscopia de infrarrojo y de resonancia magnética nuclear 1D y 2D, y análisis estructural por difracción de rayos X, y se han racionalizado los resultados mediante estudios computacionales DFT de los mecanismos de reacción. Algunos de los resultados más novedosos son: - Síntesis de complejos de renio con ligandos tridentados mediante reacciones de acoplamiento C-C entre grupos metilo desprotonados de ligandos sulfuro, fosfina o α-metilheterociclo y bipy o phen. - Formación reversible intramolecular de enlaces C-C en la posición 2 del ligando bipy. - Adición nucleofílica intermolecular del grupo bis(trimetilsilil)amido sobre el ligando phen. - Adiciones nucleofílicas intermoleculares de grupos alquilo o hidruro sobre bipy o phen. - Dimerización de grupos piridilo desaromatizados de un ligando bipy iniciados por la adición nucleofílica intermolecular de hidruro.
