Foldiak and Horvath studied the radiolysis of cyclopropane-propane and cyclopropane-propene mixtures. Horvath and coworkers" reported on the comparison between photolysis and radiolysis of the mixture cyclopropane-propane system. 

Gant and Yang studied the decay of gaseous T2 in cyclopropane (cyclopropane pressure more than 100 times that of T2). The main products are tritiated cyclopropane, propane, propene, ethylene, ethane and acetylene. Table 7 gives the yields of the main products as fractions from the number of tritium atoms, incorporated into these compounds. 

For all the binary mixtures examined in this study, molecular volumes of the components are nearly similar and hence all the binary systems are expected to exhibit ideal behavior. However, the chromatographically derived data show non-ideal behavior for CH -C H and cyclopropane-propane mixtures. The chromatographic... 

In other cases, sulfenic acid elimination can involve y-hydrogen atoms with the formation of cyclopropane derivatives. y-Klimination is favored when DMSO is the reaction solvent. An example involving l-methylsulfinyl-2-ethyl-3-phenyl propane [14198-15-3] is shown in equation 13 (45) ... 

Flammable gases and vapors include acetylene, hydrogen, butadiene, ethylene oxide, propylene oxide, acrolein, ethyl ether, ethylene, acetone, ammonia, benzene, butane, cyclopropane, ethanol, gasoline, hexane, methanol, methane, natural gas, naphtha, and propane. 

To name an alkane in which the carbon atoms form a single chain, we combine a prefix denoting the number of carbon atoms with the suffix -ane (Table 18.1). For example, CH,—CH, (more simply, CH,CH,) is ethane and CH,—CH2—CH, (that is, CH,CH2CH,) is propane. Cyclopropane, C,H6 (15), and cyclohexane, C6H12 (16), are cycloalkanes, alkanes that contain rings of carbon atoms.

Recently, Y. Yamamoto reported a palladium-catalyzed hydroalkoxylation of methylene cyclopropanes (Scheme 6-25) [105]. Curiously, the catalysis proceeds under very specific conditions, i.e. only a 1 2 mixture of [Pd(PPh3)4] and P(o-tolyl)3 leads to an active system. Other combinations using Pd(0 or II) precursors with P(o-tolyl)3 or l,3-bis(diphenylphosphino)propane, the use of [Pd(PPh3)4] without P(o-tolyl)3 or with other phosphine ligands were all inefficient for the hydroalkoxylation. The authors assumed a mechanism in which oxidative addition of the alcohol to a Pd(0) center yields a hydrido(alkoxo) complex which is subsequently involved in hydropal-ladation of methylenecyclopropane. 

The procedure (with ethylene dibromide replacing trimetliyleiie dibromide) described for cycZobutanecarboxylic acid (previous Section) does not give satisfactory results when applied to the cyc propane analogue the yield of the cyclopropane-1 1-dicarboxylic acid is considerably lower and, furthermore, the decarboxylation of the latter gives a considerable proportion (about 30 per cent.) of butyrolactone ...
