The term "alkyl" as used herein, alone or in combination, denotes a straight-chain and branched-chain saturated hydrocarbon group of 1-8 carbon atoms, for example, methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert.
butyl, or the like.
The term "alkoxy" denotes an alkyl ether wherein the "alkyl" moiety is as described above.
The term "haloalkyl" denotes an alkyl group wherein one or more of the hydrogen atoms has been replaced by "halogen".
The term "halogen" denotes fluorine, chlorine, bromine or iodine.
The term "aryl" denotes mononuclear or dinuclear aromatic groups of up to 12 carbon atoms in which one or more of the hydrogen atoms can be replaced by alkyl, alkoxy, halogen, cyano, nitro, alkanoyloxy or alkoxycarbonyl, for example, phenyl, halophenyl, dihalophenyl, methoxyphenyl, dimethoxyphenyl, nitrophenyl, tolyl, methoxycarbonylphenyl, naphthyl and the like.
The term "aryloxy" denotes an aryl ether group in which the "aryl" moiety is as previously described.
The term "aralkyl" denotes an aryalkyl group such as benzyl, phenethyl and the like
