dc.descriptionRecently, extensive studies have been conducted on the coordination chemistry of ligands with phosphinoyl groups and rhenium carbonyl precursors, leading to the formation of metal complexes with diverse nuclearity. Consequently, the reaction of halogenopentacarbonylrhenium(I) [ReX(CO)5]; X = Cl, Br with the ligand 2-bromo6-diphenylchalcogenophosphinoylpyridine, Br(C5H3N)P(Se)Ph2, was investigated in the presence of tertiary phosphines (PPh3 and P(p-Tol)3) through a one-pot reaction at toluene reflux to produce [ReX(CO)3L{κ-Se(Br(C5H3N)P(Se)Ph2)}]; X = Br, L = PPh3 (3a); X = Br, L = P(p-Tol)3 (3b); X = Cl, L = PPh3 (4a); X = Cl, L = P(p-Tol)3 (4b) complexes, in which the ligand is coordinated through the chalcogen. The new complexes were characterized using standard spectrometric and spectroscopic techniques (FTIR, NMR, MS). Furthermore, the reactivity study [ReBr(CO)5] with the sulfur-containing ligand Br(C5H3N)P(S)Ph2 was carried out in the presence of triphenylphosphine (PPh3), but no complexes were obtained due to the low nucleophilic power of sulfur.es
dc.description.abstractRecientemente, se han llevado a cabo extensos estudios sobre la química de coordinación de ligantes con grupos fosfinoílos frente a precursores carbonílicos de renio, obteniendo complejos metálicos de diversa nuclearidad. Debido a esto, se estudia la reacción del halogenopentacarbonilrenio(I) [ReX(CO)5] (X = Cl, Br) con el ligando 2-bromo-6-difenilcalcogenofosfinoilpiridina, Br(C5H3N)P(Se)Ph2, en presencia de fosfinas terciarias (PPh3 y P(p-Tol)3), a través de una reacción de un solo paso (one-pot reaction) a reflujo de tolueno, para producir los complejos [ReX(CO)3L{κSe(Br(C5H3N)P(Se)Ph2)}]; X = Br, L = PPh3 (3a); X = Br, L = P(p-Tol)3 (3b); X = Cl, L = PPh3 (4a); X = Cl, L = P(p-Tol)3 (4b), el ligando está coordinado a través del calcógeno. Los nuevos complejos fueron caracterizados utilizando técnicas espectrométricas y espectroscópicas estándar (FTIR, RMN, MS). Además, el estudio de reactividad [ReBr(CO)5] con el ligando que contiene azufre Br(C5H3N)P(S)Ph2 se realizó en presencia de trifenilfosfina (PPh3), pero no se obtuvieron complejos debido al bajo poder nucleofílico del azufre.es
