In organic chemistry, a cycloalkyne is the cyclic analog of an alkyne (−C≡C−). A cycloalkyne consists of a closed ring of carbon atoms containing one or more triple bonds. Cycloalkynes have a general formula CnH2n−4.

Cycloalkanes are hydrocarbons that contain rings of carbon atoms linked together by single bonds.

The smallest isolable cycloalkyne rings are seven-membered. Coupling 1,6-dichlorododecamethyl-hexasilane with the acetylene di-Grignard reagent gives the hexasilacyclooctyne in 46% yield. This colourless liquid photolyses in the presence of Et3 SiH to pentasilacycloheptyne, a crystalline solid, m.p. 43–45 °C (Equation (40)).

Cyclooctyne (C 8 H 12) is the smallest cycloalkyne capable of being isolated and stored as a stable compound. Chatbot answers are created from Britannica articles using AI. This is a beta feature.

In organic chemistry, a cycloalkyne is the cyclic analog of an alkyne (−C≡C−). A cycloalkyne consists of a closed ring of carbon atoms containing one or more triple bonds. Cycloalkynes have a general formula CnH2n−4.

In organic chemistry, a cycloalkene or cycloolefin is a type of alkene hydrocarbon which contains a closed ring of carbon atoms and either one or more double bonds, but has no aromatic character. Some cycloalkenes, such as cyclobutene and cyclopentene, can be used as monomers to produce polymer chains. [1] .

Comparison of the data for cycloalkenes in Table 12-5 and for cycloalkanes in Table 12-3 reveals that this expectation is realized for cyclopropene, but is less conspicuous for cyclobutene and cyclopentene. The reason for this is not clear, but may be connected in part with the C−H C − H bond strengths (see Section 12-4B).

ng Cycloalkanes General Formula: CnH(2n) Parent Chain Use the cycloalkane as the parent chain if it has . reater number of carbons than any alkyl substituent. If an alkyl chain off the …

Cycloalkanes, a fundamental class of organic compounds, possess intriguing structural characteristics that distinguish them within the realm of organic chemistry. Unlike their linear counterparts, cycloalkanes form closed-ring structures composed entirely of carbon atoms, bonded together in a cyclic fashion.

A cycloalkene is defined as a hydrocarbon with a ring of carbon atoms containing one or more double bonds that do not form an aromatic ring. These compounds are found in natural products and are involved in industrial processes like cyclohexene synthesis. You might find these chapters and articles relevant to this topic.
