Oxygen denoting attachment

The epoxides are named by numbering the alkyl chain and indicating the two carbons to which the oxygen is attached. The prefix epoxy denotes this functional group. Ethylene... [Pg.577]

Where the new bridge is attached to oxygen (or a replacement heteroatom, e.g. nitrogen in an amino sugar) already indicated in the name of the unbridged carbohydrate, the bivalent substituent prefix denotes substitution at two heteroatoms as outlined in 2-Carb-24.1 and 2-Carb-25 [method (b)]. Heteroatoms not directly bonded to the carbohydrate chain are regarded as part of the bridge. [Pg.143]

We denote acids in which the acidic proton is attached to carbon as carbon acids, those with the proton attached to oxygen as oxygen acids, and so forth for acids of other types. [Pg.139]

Fig. 8.15 Sample scenario for enhanced enantiomeric selectivity in a racemic mixture of two chiral alcohols related by inversion. An alcohol and ketone exchange two hydrogen atoms so as to produce the ketone, but with an alcohol of reverse handedness. Here A and X are distinct organic groups and dashes denote, in the upper panel, hydrogen bonds. The electronically 1 excited species G, which is formed upon excitation with light, is postulated to be given by the structure at the bottom of the figure. In this case the topmost and bottommost hydrogens are, attached to the oxygens and carbons, respectively, by half-bonds. (From Fig. 4, Ref. [259],) j...

Effects of three kinds of gases, i.e., air, nitrogen gas and oxygen gas, on the individual DTA curves of the sawdust of red lauan and that of Japanese cedar are shown in Figs. 87 and 88, respectively. The figures attached to each curve denote the exothermic peak temperatures expressed each in °C. The same is true of all the DTA curves presented herein. In this connection, the pattern of the TG curve of the sawdust of every wood species, including red lauan and Japanese... [Pg.246]

Modes of attachment of O2 to metals. P, N, and O denote phosphine, amine, and oxygen ligands, respectively. [Pg.196]

The boiling points of these compounds, however, are also affected by the polar character of the C—Z bond (where Z denotes N, O, F, Cl, or Br) because nitrogen, oxygen, and the halogens are more electronegative than the carbon to which they are attached. [Pg.83]

A SSS denotes a four-ring with a single Al-substitution and a proton attached to the oxygen atom bridging the A1 and Si. [Pg.507]

P the currently recommended abbreviation or symbol for bound phosphate and all its ionized forms. Attached to one other symbol, it denotes PO3H2 (and its ionized forms). Attached to two other symbols, it denotes PO2H (and its ionized form). The bridge oxygen atom(s) to attached groups is (are) therefore not included. [Eur. J. Biochem. 1 (1967) 259-266]... [Pg.481]

Structural differences among arise from the type, number, position and orientation of the substituents, as well as the number and position of double bonds. A substituent containing oxygen is denoted by adding to the name of the parent hydrocarbon the appropriate prefix, e.g. hydroxy, oxo, or suffix, e.g. -ol, -one, preceded by the number of the carbon to which it is attached and its orientation if appropriate if hydroxyl and keto groups occur in the same steroid the former is denoted by a prefix and the latter by a suffix, e.g. 3o-hydroxy-5a-androstan-17-one. The presence of double bond(s) is indicated by changing the terminal... [Pg.642]
