The sum of all results is consistent with the formation of both the aryl cation and the aryl radical in the aqueous acid system without copper, and with the dominance of the aryl radical in the presence of copper. The product ratios are also qualitatively consistent with the hypothesis that the reactivity of aryl cations with nucleophiles is close to that of a diffusion-controlled process (see Sec. 8.3), and that aryl radicals have arylation rate constants that are about two orders of magnitude smaller than that for diffusion control (0.4-1.7 X 107 m-1s-1 Kryger et al., 1977 Scaiano and Stewart, 1983). Due to the relatively low yields of these dediazoniations in the pentyl nitrite/benzene systems, no conclusions should be drawn from the results.

The lUPAC name of cannabidiol is 2-[(lS, 6iI)-3-methyl-6-prop-l-en-2-yl-l-cyclohex-2-enyl]-5-pentyl-benzene-1,3-diol. Cannabidiol (CBD, 2.9) in its acidic form cannabidiolic acid (CBDA, 2.10) is the second major cannabinoid in C. sativa besides A9-THC. As already mentioned for A9-THC, variations in the length of the side chain are also possible for CBD. Important in this context are the propyl side chain-substituted CBD, named cannabidivarin (CBDV, 2.11), and CBD-C4 (2.12), the homologous compound with a butyl side chain. Related to the synthesis starting from CBD to A9-THC as described in Sect. 3.1, it was accepted that CBDA serves as a precursor for THCA in the biosynthesis. Recent publications indicate that CBDA and THCA are formed from the same precursor, cannabigerolic acid (CBGA), and that it is unlikely that the biosynthesis of THCA from CBDA takes place in C. sativa. 

Similarly, under a variety of reaction conditions, alkylation of benzene with either 2-chloro or 3-chloropentane gives rise to a mixture of both 2-pentyl- and 3-pentylbenzene.34...

Two 1,3,5-trisubstituted benzenes, A,iV, iV"-tris[3-(acetylhydroxyamino)propyl]-l,3,5-benzenetricarboxamide (28) and A,iV, iV"-tris[5-(acetylhydroxyamino)pentyl]-l,3,5-benzenetricarboxamide (29), were prepared by Lee and coworkers . Both analogs did not promote growth in various strains of E. coli.

The first step involves hydride abstraction and a phenonium ion intermediate.198 The low yields are accounted for by the ready dealkylation of sec- and tert-pentyl-benzenes under the reaction conditions (see discussion below). 

Suzuki et al. [Ill] screened three solvents—methylene chloride, diethyl ether, and benzene—to determine their ability to produce optimum elution of phthalic acid monoesters sorbed on a styrene divinylbenzene polymer (Figure 2.40). The effect of elution solvent strength on the recovery of the free acid form of the monomethyl (MMP), ethyl (MEP), -propyl (MPRP), K-butyl (MBP), K-pentyl (MPEP), and -octyl (MOP) phthalates is compared. The phthalic acid monoesters are arranged in Figure 2.40 in the order of increasing number of carbons in the alkyl chain, which in turn is roughly correlated with an increase in hydrophobicity.
