单词 | phenyl carbonate |
释义 | > as lemmasphenyl carbonate b. Forming the systematic, semi-systematic, or trivial names of organic compounds containing one or more phenyl groups, as phenyl carbonate, phenyl cyanide, phenyl phosphate.Recorded earliest in phenyl alcohol n., phenylamine n. at Compounds 2.Also with locant.In systematic substitution nomenclature phenyl is now normally written as one word with the item to which it is prefixed. Two-word names are used chiefly in functional class nomenclature, where the second (or final) word is a class term, as of an acid or acid derivative, oxygen or carbonyl compound, halide or pseudohalide, etc. In later systematic use, therefore, there is usually a semantic difference between the two forms, as between phenyl acetate (the phenyl ester of acetic acid) and phenylacetate (a salt or ester of phenylacetic acid), although this rule of chemical nomenclature is not always applied consistently.
