Exempel på hur man kan använda CYCLOPROPANE i en mening

• The cycloalkanes without side chains (also known as monocycloalkanes) are classified as small (cyclopropane and cyclobutane), common (cyclopentane, cyclohexane, and cycloheptane), medium (cyclooctane through cyclotridecane), and large (all the rest).
• Freund treated 1,3-dibromopropane with sodium, causing an intramolecular Wurtz reaction leading directly to cyclopropane.
• The simplest alicyclic compounds are the monocyclic cycloalkanes: cyclopropane, cyclobutane, cyclopentane, cyclohexane, cycloheptane, cyclooctane, and so on.
• The Simmons–Smith reaction is an organic cheletropic reaction involving an organozinc carbenoid that reacts with an alkene (or alkyne) to form a cyclopropane.
• Methylcycloalkanes are classed into compounds with small, normal and bigger cycloalkanes, where cyclopropane and cyclobutane are the small ones, cyclopentane, cyclohexane, cycloheptane are the normal ones and the rest are the bigger ones.
• Cycloalkanes generally have less ring strain than cycloalkenes, which is seen when comparing cyclopropane and cyclopropene.
• These crystallographic studies have been used to demonstrate that the internuclear distance between the atoms at the base of the cyclopropenyl structure is indeed longer than would be expected for a normal cyclopropane molecule, while the external bonds appear to be shorter, indicating involvement of the internal cyclopropane bond in charge delocalization.
• The bullvalene molecule is a cyclopropane platform with three vinylene arms conjoined at a methine group.
• The Skattebøl rearrangement is an organic reaction for converting a geminal dihalo cyclopropane to an allene using an organolithium base.
• demonstrated the co-occurrence of malvalic acid and the corresponding cyclopropane acids in several types of seeds.
• Cypenamine is a homolog of tranylcypromine, containing an expanded alicyclic ring that is two methylene units larger than the highly strained/reactive cyclopropane.
• A rotane is a hydrocarbon consisting of a central cycloalkane ring with cyclopropane units spiro-linked to each corner.
• Some inhaled anaesthetics used for general anesthesia, such as cyclopropane and halothane, may reduce the effect of oxytocin and ergometrine.
• The vinylcyclopropane rearrangement or vinylcyclopropane-cyclopentene rearrangement is a ring expansion reaction, converting a vinyl-substituted cyclopropane ring into a cyclopentene ring.
• A single cyclopropane diastereomer was isolated in 55% yield after diazoketone formation and cyclization.
• Metal-catalyzed cyclopropanations are chemical reactions that result in the formation of a cyclopropane ring from a metal carbenoid species and an alkene.
• A cyclopropyl group is a chemical structure derived from cyclopropane; it is typically produced in a cyclopropanation reaction.
• Olah, Mario Barzaghi, Massimo Simonetta (1972), "Heats of formation of protonated cyclopropane, methylcyclopropane, and ethane".
• The molecule contains three asymmetric carbon atoms, there is cis-trans isomerism at the cyclopropane ring, and cis-trans isomerism at the carbon-carbon double bond of the alkene.
• In the case at the right the cyclopropane EAG activates the aliphatic C–H bonds adjacent to it via hyperconjugation (oxygen and nitrogen heteroatoms can also do this).
