Friedel-Crafts alkylation of benzene and toluene with olefinic C6 hydrocarbons and esters
Black, Kenneth D.,Gunstone, Frank D.
, p. 79 - 86 (1996)
To assist our study of the reaction of toluene and other aromatic compounds with methyl oleate and other olefinic esters, benzene and toluene have been alkylated under Friedel-Crafts conditions with hex-1-ene, hex-3-ene, methyl hex-3-enoate and methyl hex-3-enedioate. The products were isolated and identified by NMR and mass spectrometric procedures.

5-Cyano-7-(dimethylamino)-5-phenylheptanoic acid (3; R1=H, R2=CN) and its derivatives could not be cyclised to benzosuberones but yielded with PPA, 3-(dimethylaminoethyl)-3-phenyl-2,7(1H)-dioxoazepane (6) and 6-(dimethylaminoethyl)-6

Acetophenone-initiated photodegradation of cis-2-methoxy-4-methyltetrahydropyran (7) in benzene solvent produced six products.The structures of the products, and studies using optically active 7, showed that hydrogen abstraction occurs at both C-2 and C-6 of the tetrahydropyran ring.The products derived from the C-2 radical indicated two pathways for this radical: ring opening and loss of methyl, which is consistent with previous work on other similar systems.Results with optically active 7 showed that the ring-opening pathway is irreversible.Generation of an open-chain radical independently also showed that cyclization to a six membered ring does not occur.The products from the photodegradation were trans-2-methoxy-6-methyltetrahydropyran (8), methyl hexanoate (10), 6-methyltetrahydropyran-2-one (9), methyl 5-phenylhexanoate (11), 1,7-dimethyl-7-phenyl-6,8-dioxobicyclooctane (13), and 2-methoxy-2-(1-phenyl-1-hydroxyethyl)-6-methyltetrahydropyran (12).The yield of lactone 9 was found to be sensitive to the amount of residual oxygen present during the photolysis.
