2-Cyclopentenone is the organic compound with the chemical formula (CH 2) 2 (CH) 2 CO. 2-Cyclopentenone contains two functional groups, a ketone and an alkene. It is a colorless liquid. It is a colorless liquid.
[5] Cyclopentobarbital, a drug made from cyclopentanone. Cyclopentanone is also used to make cyclopentamine, the pesticide pencycuron, and pentethylcyclanone. [5] It is also used as a precursor to cubane-1,4-dicarboxylate, which is used to synthesize other substituted cubanes, such as the high explosives heptanitrocubane and octanitrocubane. [6]
Methylcyclopentane is an organic compound with the chemical formula CH 3 C 5 H 9. It is a colourless, flammable liquid with a faint odor. It is a colourless, flammable liquid with a faint odor. It is a component of the naphthene fraction of petroleum usually obtained as a mixture with cyclohexane .
2-Hydroxy-3-methyl-2-cyclopenten-1-one is an organic compound related to 1,2-cyclopentanedione. It is the enol tautomer of the diketone 3-methylcyclopentane-1,2-dione. Being an enol, the compound is often called methylcyclopentenolone. It is a colorless solid.
Cyclopentene was first prepared by Carl Gärtner in 1893 from iodocyclopentane with potassium hydroxide.He named it pentamethenylene (German: Pentamethenylen). [3] ...
Cyclopentane (also called C pentane) [4] is a highly flammable alicyclic hydrocarbon with chemical formula C 5 H 10 and CAS number 287-92-3, consisting of a ring of five carbon atoms each bonded with two hydrogen atoms above and below the plane. It is a colorless liquid with a petrol-like odor.
These isomers are the organic precursor to the methylcyclopentadienyl ligand (C 5 H 4 Me, often denoted as Cp′), commonly found in organometallic chemistry. As with cyclopentadiene , methylcyclopentadiene is prepared by thermal cracking of its Diels–Alder dimer, followed by distillation for removal of cyclopentadiene, a common impurity.
The Pauson–Khand (PK) reaction is a chemical reaction, described as a cycloaddition.In it, an alkyne, an alkene, and carbon monoxide combine into a α,β-cyclopentenone in the presence of a metal-carbonyl catalyst [1] [2] Ihsan Ullah Khand (1935–1980) discovered the reaction around 1970, while working as a postdoctoral associate with Peter Ludwig Pauson (1925–2013) at the University of ...
