Acetylpropionyl, also known as acetyl propionyl or 2,3-pentanedione, [1] is an organic compound, specifically a diketone. [2] Uses for acetylpropionyl include as a: Solvent for cellulose acetate, paints, inks, and lacquers; Starting material for dyes, pesticides, and drugs
2-Methyl-2,4-pentanediol (MPD) is an organic compound with the formula (CH 3) 2 C(OH)CH 2 CH(OH)CH 3. This colourless liquid is a chiral diol . It is produced industrially from diacetone alcohol by hydrogenation . [ 4 ]
George Kleinspehn reported that the Fischer–Fink connectivity could be forced to occur exclusively, by the use of diethyl oximinomalonate in the synthesis, with 2,4-pentanedione, or its 3-alkyl substituted derivatives. Yields were high, around 60%, and this synthesis eventually came to be one of the most important in the repertory. [13]
Thomson scattering is a model for the effect of electromagnetic fields on electrons when the field energy is much less than the rest mass of the electron .In the model the electric field of the incident wave accelerates the charged particle, causing it, in turn, to emit radiation at the same frequency as the incident wave, and thus the wave is scattered.
Exchange interaction is the main physical effect responsible for ferromagnetism, and has no classical analogue. For bosons, the exchange symmetry makes them bunch together, and the exchange interaction takes the form of an effective attraction that causes identical particles to be found closer together, as in Bose–Einstein condensation .
The anhydrous form exists as the tetramer [Co(acac) 2] 4. Like the trimeric nickel complex, this tetramer shows ferromagnetic interactions at low temperatures. [21] Ir(acac) 3 and Rh(acac) 3 are known. A second linkage isomer of the iridium complex is known, trans-Ir(acac) 2 (CH(COMe) 2)(H 2 O).
