With No Functional Group

There also exists a type of resin with no functional groups attached. This resin offers no capacity to the system but increases regeneration efficiency in mixed-bed exchangers. These inert resins are of a density between cation and anion resins and when present in... 

It is possible to perform the conversion CH2 C=0 on an alkane, with no functional groups at all, though the most success has been achieved with substrates in which all CH2 groups are equivalent, such as unsubstituted cycloalkanes. One method uses H2O2 and bis(picolinato)iron(II). With this method, cyclohexane was converted with 72% efficiency to give 95% cyelohexanone and 5% cyclohexanol. ... 

Osmium-catalysed dihydroxylation of olefins is a powerful route towards enantioselective introduction of chiral centers into organic substrates [82]. Its importance is remarkable because of its common use in organic and natural product synthesis, due to its ability to introduce two vicinal functional groups into hydrocarbons with no functional groups [83]. Prof. Sharpless received the 2001 Nobel Prize in chemistry for his development of asymmetric catalytic oxidation reactions of alkenes, including his outstanding achievements in the osmium asymmetric dihydroxylation of olefins. 

Another characteristic in the octane spectrum is the absence of any identifiable C—C stretching absorptions. (Table 12-1 shows that C—C stretching absorptions occur around 1200 cm-1.) Although there are seven C—C bonds in octane, their dipole moments are small, and their absorptions are weak and indistinguishable. This result is common for alkanes with no functional groups to polarize the C—C bonds. 

Alkyl-, alkenyl-, or alkynylpyrazines [usually with no functional groups attached to the alkyl substituent(s)] may be converted into other such pyrazines in several ways, as illustrated in the following examples ... 

Cyclic alkenes with no functional groups are also readily and selectively fluorinated. Cyclo-heptene, for example, is fluorinated in 40% yield to 1.2-difluorocycloheptanc (14). ... 

Even in molecules with no functional groups which are expected to interact with silanol sites on silica gel through hydrogen bonding, adsorption on solid surfaces modifies their electronic states and their photophysical processes but the mechanism of adsorption interaction is not elucidated in detail. 

Aromatics and saturated alkanes with no functional groups... 

The ability of aerobes to incorporate oxygen into organic molecules via oxygenases allows these microbes to utilize aromatic and saturated alkanes with no functional groups (e.g., benzene). 

Identifying Monofunctional Molecules and Those with No Functional Group... 

In Chapter 11, we developed one other important technique installing functionality in a compound with no functional groups ... 

Keesom Orientation Forces. These forces result from the interaction of two permanent dipoles, of which the hydrogen bond is the most important. Hydrogen bonds are stronger than dispersion or inductive forces. If the two components have the same vapor pressure, separation can be achieved on the basis of several properties. These properties are (in the order of then-ease of separation) (1) difference in the functional groups, (2) isomers with polar functional groups, and (3) isomers with no functional groups. 

Polymers resulting from addition polymerisation will have repeat units with no functional groups in the actual chain...
