The derived enthalpies of formation of the n-propyl and ec-butyl lithiated methoxy ethers are —260 and —275 kJmon, respectively, from equation 16, the enthalpies of protodelithiation, the enthalpy of formation of n-butyl lithium from Table 1 and of liquid n-butane, and the measured enthalpies of formation of methyl n-propyl ether (Iq, —266.0 ...

Positional Isomers Positional isomers differ in the position where a functional group occurs in a molecule. In Figure 1.2.1, 1-butanol and 2-butanol are positional isomers with the position of the hydroxyl group indicated by the prefixes 1 and 2, respectively. Similarly, methyl n-propyl ether and diethyl ether are positional isomers, as reflected in their synonym names 2-oxapentane and 3-oxapentane, with the prefixes 2 and 3 indicating the position of the ether group, respectively. 

The latter expression (30), which parallels that for the Z = NH case, is seen to give an essentially indistinguishable result to the former (29), which directly uses methyl n-propyl ether as an input number ...

The value of ((i(H2)=0.4 appears to be the most reliable. The higher values including 0.5 which are still currently used would give primary processes) > 1 for many systems such as N2O (166), methanol (127), ethanol (128), isopropanol (129), di-t-butyl ether (87) and methyl-n-propyl ether (88), an unreasonable result. However, using <(>(H2)=0.4, (Ksum of primary processes) approaches or equals but never exceeds unity. If normalized to the same actlnometer quantum yield value, results from different laboratories, for example, the H2 yield of 1M methanol in water ( cf. 127,166-168), agree within 10 percent. 

More recently, detailed studies were presented by the reviewers group on diethyl ether (177), methyl n-propyl ether (88), t-butyl methyl ether (86), di-t-butyl ether (87), and 2-methoxyethanol (159), and more restricted studies (178) on ethyl n-propyl ether, ethyl isopropyl ether. Isopropyl methyl ether, and n-butyl methyl ether. 

Carbon-carbon bond scission is rather unimportant in diethyl ether (< 0.5%) and methyl n-propyl ether (< 2%), but is enhanced somewhat in t-butyl methyl ether (= 4.5%) and di-t-butyl ether (7%). The reverse has been found regarding the formation of hydrogen. 

As seen in Scheme 14, molecular elimination processes (including cage disproportionation reactions) account for about half of the primary decomposition. This is in contrast to the behavior of the Isosteric ethers such as diethyl (177) and methyl n-propyl ethers (88), where these processes are rather less important (Schemes 6 and 7). It is not known whether the formaldehyde formed in reaction 4 (Scheme 14) incorporates the carbon atom from methylene or methyl. 

Capture of phenyl cations with methyl n-propyl ether gives products in which rearrangement has taken place.Initial capture gives the oxonium ion drawn to the left in equation 14. Most of this ion eliminates propene, and deprotonation of the resulting ion affords anisole (PhOR, where R = methyl), which constitutes 75% of the radiochemical yield. Among the other products are isopropyl phenyl ether (roughly 3% of the radiochemical yield, about 3 times more abundant than -propyl...
