A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H 2n−1. [2] Typically an alkyl is a part of a larger molecule. In structural formulae, the symbol R is used to designate a generic (unspecified) alkyl group. The smallest alkyl group is methyl, with the formula −CH 3 ...
Large alkyne-containing carbocycles may be virtually unstrained, while the smallest constituents of this class of molecules may experience so much strain that they have yet to be observed experimentally. [1] Cyclooctyne (C 8 H 12) is the smallest cycloalkyne capable of being isolated and stored as a stable compound. [2]
The bridged bicyclic norbornane, formally bicyclo[2.2.1]heptane The spirocyclic compound spiro[5.5]undecane DABCO (1,4-diazabicyclo[2.2.2]octane) is often incorrectly depicted with one skewed ethylene group for the sake of clarity. A bicyclic molecule (from bi 'two' and cycle 'ring') is a molecule that features two joined rings. [1]
The dialkylating group is often a 1,3-, 1,4-, etc. dihalide. [9] In some cases the dialkylating group is a dilithio reagent, such as 1,5-dilithiopentane. [ 10 ] For generating spirocycles containing a cyclopropane ring, cyclopropanation with cyclic carbenoids has been demonstrated.
Alkyl cycloalkanes are chemical compounds with an alkyl group with a single ring of carbons to which hydrogens are attached according to the formula C n H 2n . They are named analogously to their normal alkane counterpart of the same carbon count: methylcyclopropane , methylcyclobutane , methylcyclopentane , methylcyclohexane , etc. [ 1 ]
Norbornane (also called bicyclo[2.2.1]heptane). Unsubstituted cycloalkanes that contain a single ring in their molecular structure are typically named by adding the prefix "cyclo" to the name of the corresponding linear alkane with the same number of carbon atoms in its chain as the cycloalkane has in its ring.
Cycloalkylamines are chemical compounds featuring a cycloalkyl group and an amine. [1] Some examples include propylhexedrine, cyclopentamine, cypenamine, and tranylcypromine. Some chemicals act as stimulants. [2]
With their repeated – CH 2 units, the alkanes constitute a homologous series of organic compounds in which the members differ in molecular mass by multiples of 14.03 u (the total mass of each such methylene-bridge unit, which comprises a single carbon atom of mass 12.01 u and two hydrogen atoms of mass ~1.01 u each).
