With the volume and accessibility of scientific research increasing across the world, it has never been more important to continue building the reputation for quality and ethical publishing we’ve spent the past two centuries establishing.In an article, 1271-48-3, molcular formula is C12H10FeO2, belongs to iron-catalyst compound, introducing its new discovery., Application of 1271-48-3
The crystal architecture, stability, and behavior with temperature of bis(formyl)ferrocene, [Fe(eta5-C5H4CHO)2], have been investigated by variable-temperature X-ray diffraction experiments, differential scanning calorimetry, and thermogravimetry experiments. [Fe(eta5-C5H4CHO)2] is present with two independent molecules with cisoid and transoid relative orientations of the two formyl groups in the crystals obtained from the reaction sequence (phase RT-1). The role of C-H- – -O interactions involving the formyl groups has been examined. When RT-1 is heated, the first irreversible phase transition to a plastic phase (phase HT) is observed at ca. 38C (311 K). When it is cooled, phase HT transforms into a new room-temperature phase (RT-2). Once RT-2 has been formed, the system switches reversibly between HT and RT-2 (transition temperature in the heating cycles ca. 35C), while RT-1 can no longer be obtained. Further heating of phase HT shows the occurrence of an exothermic reaction at ca. 150C (423 K) leading to the formation of a ferrocene-based polymer.
In the meantime we’ve collected together some recent articles in this area about 1271-48-3 to whet your appetite. Happy reading! Application of 1271-48-3
