3 Brief Demonstration of the General Nomenclature Rules
3.5
radicof.: a,a- Dimethylbenzyl hydroperoxide
subs tit.: (1- Phenyl-l-methylethyl)dioxidane
~8, . . . . . 8, . . . . . 8....
Butyl hydropentasulfide

H Butylpentasulfane
3-Pyridyl hydro trioxide
Pyridin-3-yltrioxidane
Ethers and Thioethers
Ethers are named either radicofunctionally or substitutively, with a clear
preference for the first method in simple cases.
lEt radicof.: Diethyl ether
o substit.: Ethoxyethane
\ Et CA:
Oxybisethane
The previous example persuasively underscores how much simpler systematic nomenclature would be and above all how much easier to teach if
general recognition of fully systematic names could eventually be reached
for each and all parent hydrides (see Table 14); in the present case this
would give the substitutive name diethyloxidane.
CI-CHr CHr O-CH=CH2
H3C-O-CH2-CH2-0-CH3
(2-Chloroethyl)vinyl ether
(2-Chloroethoxy)ethene
(1,2,4-Triazin-6-yl) (5-nitro-3-pyridyl)
ether
6-(5-Nitro-3-pyridyloxy)-1,2,4-triazine
1,2-Dimethoxyethane; glycol dimethyl
ether is not a systematic name;
radicofunctionally it would have
to read: ethylene or ethane-l ,2-diyl
dimethyl ether!
