Alkoxy alkane system

We have been using the common nomenclature of ethers, which is sometimes called the alkyl alkyl ether system. The IUPAC system, generally used with more complicated ethers, is sometimes called the alkoxy alkane system. Common names are almost always used for simple ethers. 

Simple (symmetrical) ethers have the general formula R—O—R or Ar—O—Ar mixed (unsymmetrical) ethers are R—O—R or Ar—O—Ar or Ar—O—R. The derived system names R and Ar as separate words and adds the word ether. In the IUPAC system, ethers (ROR) are named as alkoxy- (RO-) substituted alkanes. Cyclic ethers have at least one O in a ring. 

The fungitoxic and systemic properties of other alkoxy, alkylamino and alkylthio trichloroethylformamide (Carter et al., 1975a) and bis[(l-formamido-2,2,2-trichloro)ethylamino]alkane (Carter et al., 197Sb) derivatives have also been investigated (Loeffler et al., 1981). 

For longer chain alkanes ( 04) the reaction mechanism becomes more complex due to the IsomerIzatIons of the alkoxy radicals (47, 48), and to the fact that addition of NO to the alkyl-peroxy radicals (49) becomes more Important than NO to NO2 oxidation. For the alkenes and aromatic hydrocarbons the oxidation mechanisms In the atmosphere are more complex, and discussions of these systems, along with a more detailed treatment of the alkanes, are given later. 

Ethers contain an oxygen attached to two carbons as the characteristic functional group. In the lUPAC system, ethers are named as alkoxy derivatives of alkanes. The —O—R group is the alkoxy group that may have names such as methoxy (—O—CH3) or ethoxy (—0—CH2CH3). Objective 7, Exercise 3.42... 

The lUPAC system for naming ethers treats them as alkanes that bear an alkoxy substituent— that is, as alkoxyalkanes. The smaller substituent is considered part of the alkoxy group and the larger chain defines the stem. 

Ethers can be viewed as alkane or aromatic compounds containing the group RO— this group is known as the alkoxy group. The lUPAC system for naming ethers treats them as alkanes that bear an alkoxy substituent, that is, as alkoxyalkanes. The smaller substituent is considered part of the alkoxy group and the larger substituent defines the stem. Thus, for example, the lUPAC name for ethylmethyl ether is methoxyethane, and for anisole, it is methoxybenzene.
