Methylenecyclopropane is an organic compound with the formula (CH2)2CCH2. It is a colourless easily condensed gas that is used as a reagent in organic synthesis.
Cyclopentene is a chemical compound with the formula C5H8. It is a colorless liquid with a petrol-like odor. It is one of the cycloalkenes.
phenylacetylene · phenyl-acetylene · phenylethyne
Phenylacetylene is an alkyne hydrocarbon containing a phenyl group. It exists as a colorless, viscous liquid. In research, it is sometimes used as an analog for acetylene; being a liquid, it is easier to handle than acetylene gas.
1,2,3,4,5-pentamethyl-cyclopentadiene · 1,2,3,4,5-pentamethylcyclopentadiene
1,2,3,4,5-Pentamethylcyclopentadiene is a cyclic dialkene with the formula C5Me5H (Me = CH3). 1,2,3,4,5-Pentamethylcyclopentadiene is the precursor to the ligand 1,2,3,4,5-pentamethylcyclopentadienyl, which is often denoted Cp* (to signify the five methyl groups radiating from the periphery of this ligand as in a five-pointed star). In contrast to less-substituted cyclopentadiene derivatives, Cp*H is not prone to dimerization.
936-52-7 (99447-37-7, 936-52-7)
norbornene · norbornylene · 2-norbornene
Norbornene or norbornylene or norcamphene is a bridged cyclic hydrocarbon. It is a white solid with a pungent sour odor. The molecule consists of a cyclohexene ring with a methylene bridge between C-3 and C-6.
Indoline is an aromatic heterocyclic organic compound with the chemical formula C8H9N. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing ring. The compound is based on the indole structure, but the 2-3 bond is saturated.
