A functional group characterized by two alkoxy (OR) groups connected to the same carbon atom.Acetals can be used as protecting groups for aldehydes or ketones.
A compound that has the general formula R3N, where R may be H or a hydrocarbon group. (Section 16.7)
A compound containing an sp3 -hybridized nitrogen atom bonded to one, two, or three carbon atoms
A steroid hormone, such as testosterone, that mediates the development of sexual characteristics of males.
An intramolecular Claisen condensation.
Glass transition temperature (TG)
The temperature at which a polymer undergoes the transition from a hard glass to a rubbery state
A reaction that involves the addition of X2 (either Br2 or Cl2) across an alkene.
High-resolution mass spectrometry
Instrumentation that is capable of separating ions that differ in mass by as little as 0.0001 amu
The short-range attractive forces operating between the particles that make up the units of a liquid or solid substance. These same forces also cause gases to liquefy or solidify at low temperatures and high pressures. (Chapter 11: Introduction)
lithium dialkyl cuprate
A nucleophilic compound with the general structureR2CuLi.
Compounds formed when hydrogen reacts with transition metals; these compounds contain the hydride ion, H-. (Section 22.2)
An electrophilic aromatic substitution reaction that involves the installation of a nitro group (NO2) on an aromatic ring.
Radiation that does not have sufficient energy to remove an electron from a molecule. (Section 21.9)
In NMR spectroscopy, a technique in which only the one-bond couplings are observed. CH3 groups appear as quartets, CH2 groups appear as triplets, CH groups appear as doublets, and quaternary carbon atoms appear as singlets.
A graphic representation of the equilibria among the solid, liquid, and gaseous phases of a substance as a function of temperature and pressure. (Section 11.6)
Principle of microscopic reversibility
This principle states that the sequence of transition states and reactive intermediates in the mechanism of any reversible reaction must be the same, but in reverse order, for the reverse reaction as for the forward reaction
Reversibly creating an unreactive group for the purpose of preventing a functional group from potentially reacting to give an unwanted product or products
In NMR spectroscopy, a signal that is comprised of five peaks.
A unimolecular nucleophilic substitution reaction.
A rule stating that the major product of a b-elimination reaction is the most stable alkene; that is, it is the alkene with the greatest number of substituents on the carboncarbon double bond
