Melting point: −90 °C; −130 °F; 183 K Boiling point: 39 to 43 °C; 102 to 109 °F; 312 to 316 K ... Cyclopentadiene is an organic compound with the formula C 5 ...
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
At temperatures above about 125 °C in the vapor phase, dissociation to cyclopentadiene monomer starts to become thermodynamically favored (the dissociation constant K d = [cyclopentadiene] 2 / [dicyclopentadiene] > 1). For instance, the values of K d at 149 °C and 195 °C were found to be 277 and 2200, respectively. [10]
Melting point: −135 °C (−211 °F; 138 K) Boiling point: ... It can also be produced by the catalytic hydrogenation of cyclopentadiene. [6] Reactions
Magnesocene is a white solid at room temperature. [1] It has a melting point of 176 °C, though at atmospheric pressures it sublimes at 100 °C. [1] Unlike ferrocene, magnesocene displays slight dissociation and subsequent ion association in polar, electron-donating solvents (such as ether and THF).
Chloro(cyclopentadienyl)bis(triphenylphosphine)ruthenium is the organoruthenium half-sandwich compound with formula RuCl(PPh 3) 2 (C 5 H 5). It as an air-stable orange crystalline solid that is used in a variety of organometallic synthetic and catalytic transformations. The compound has idealized C s symmetry.
Melting point: −22 °C (−8 °F; 251 K) Boiling point: ... Cotton, and Wilkinson who produced it by the reaction of cobalt carbonyl with cyclopentadiene. [2]
Cyclopentadienyliron dicarbonyl iodide is an organoiron compound with the formula (C 5 H 5)Fe(CO) 2 I. It is a dark brown solid that is soluble in common organic solvents. (C 5 H 5)Fe(CO) 2 I, or FpI as it is often known, is an intermediate for the preparation of other organoiron compounds such as in ferraboranes.
