Ligustrum also contains a unique volatile oil consisting primarily of esters and alcohols, with lesser amounts of thioketones, hydrocarbons, and traces of amines and aldehydes, but no terpene hydrocarbons. Major components of the volatile oil include ethyl acetate (18.95%), thioketone (8.56%), a-butyl-benze-nemethanol (5.6%), 4-acetyloxy-2-butanone (5.46%), 1-phenyl-1,2-butanediol (4.12%), 1,2-diphenyl-l,2-ethanediol (3.92%), hydra-zine-methyl-oxalate (3.52%), a,a,4-tri-methyl-3-cyclohexene-methanol (3.24%), 1-methyl-l-propyl-hydrazine (2.60%), and (Z)-1 -(1 -ethoxy-ethoxy)-3-hexene (1.89%). ... 

Catalytic activity tests for cyclohexene hydrogenation were carried out for 3 hours at 60 °C in a Parr reactor (40 mL), magnetically stirred (1100 rpm), using about 30 mg of the hybrid catalyst, 10 mL of a 5 vol.% of a cyclohexene methanol solution and 10 bar H2. In the case of the homogeneous test, 0.8 mg (2 pmol) of the Rh(NN)Si complex was used. Product analysis was performed by Gas Chromatography (HP6890 Series II, capillary column HP-1 Methyl Siloxane, 30 m x 250 pm x 0.25 pm, FID detector) after each catalytic run. 

A portion of the product was heated to reflux with methanolic sodium methoxide to convert it into the thermodynamic mixture of trans- (ca. 65%) and cis- (ca. 35%) isomers. Small amounts of the isomers were collected by preparative gas chromatography using an 8 mm. by 1.7 m. column containing 15% Carbowax 20M on Chromosorb W, and each isomer exhibited the expected spectral and analytical properties. The same thermodynamic mixture of isomers was prepared independently by lithium-ammonia reduction5 of 2-allyl-3-methyl-cyclohex-2-enone [2-Cyclohexen-l-one, 3-methyl-2-(2-propcnyl)-],6 followed by equilibration with methanolic sodium methoxide.

Examination of the reactions of a wide variety of olefins with TTN in methanol (92) has revealed that in the majority of cases oxidative rearrangement is the predominant reaction course (cf. cyclohexene, Scheme 9). Further examples are shown in Scheme 18, and the scope and limitations of this procedure for the oxidative rearrangement of various classes of simple olefins to aldehydes and ketones have been defined. From the experimental point of view these reactions are extremely simple, and most of them are... 

By studying the NMR spectra of the products, Jensen and co-workers were able to establish that the alkylation of (the presumed) [Co (DMG)2py] in methanol by cyclohexene oxide and by various substituted cyclohexyl bromides and tosylates occurred primarily with inversion of configuration at carbon i.e., by an 8 2 mechanism. A small amount of a second isomer, which must have been formed by another minor pathway, was observed in one case (95). Both the alkylation of [Co (DMG)2py] by asymmetric epoxides 129, 142) and the reduction of epoxides to alcohols by cobalt cyanide complexes 105, 103) show preferential formation of one isomer. In addition, the ratio of ketone to alcohol obtained in the reaction of epoxides with [Co(CN)5H] increases with pH and this has been ascribed to differing reactions with the hydride (reduction to alcohol) and Co(I) (isomerization to ketone) 103) (see also Section VII,C). 

The second mode of addition of alcohols to olefins, to produce ethers, has been found to occur only with cyclic olefins. Thus in 1966 Kropp reported that cyclohexenes (39)-(42) produce tertiary ethers upon photolysis in methanol in the presence of high-energy sensitizers such as benzene, toluene, or xylene<79) ... 

Kwart and Khan investigated the copper-catalyzed decomposition of benzenesulphonyl azide both in methanol 33) and in cyclohexene 34>. No reaction occurs between benzenesulphonyl azide and cyclohexene at 100 °C but the addition of copper powder causes a smooth decomposition to take place yielding an impressive array of products 34>. The major ones are benzenesulphonamide 18 (37%), the aziridine 19 (15%) and the lV-(l-cyclohexenyl)benzenesulphonamide 20 (17%) (Scheme 2). Some traces of cyclohexyl azide were also found but the addition of hydro-quinone eliminated its formation. 

Tetrahydrobenzyl alcohol (( )3-cyclohexenene-l-methanol) and 30% aqueous hydrogen peroxide were purchased from Fluka, AG. 3-Cyclohexene-1-carboxylic acid and cis-4-cyclohexene-l,2-dicarboxylic acid were used as purchased from Lancaster Chemical Co. Methyl iodide, acetic anhydride, Oxone (potassium peroxymonosulfate), Aliquot 336 (methyl tri-n-octylammonium chloride), sodium tungstate dihydrate and N,N-dimethylaminopyridine (DMAP) were purchased from Aldrich Chemical Co. and used as received. 3,4-Epoxycyclohexylmethyl 3, 4 -epoxycyclohexane carboxylate (ERL 4221) and 4-vinylcyclohexene dioxide were used as purchased from the Union Carbide Corp. (4-n-Octyloxyphenyl)phenyliodonium hexafluoroantimonate used as a photoinitiator was prepared by a procedure described previously (4). 

Into a 100 mL round bottom flask fitted with a magnetic stirrer, and a condenser were placed 10.09 g (0.08 mol) of 3-cyclohexene-1-carboxylic acid, 12.81 g (0.40 mol) of methanol and 1.56 g (0.016 mol) of concentrated sulfuric acid. The reaction mixture was heated under reflux for 5 hr in an oil bath. After this time, the reaction mixture was diluted with water and then extracted several times with ether. The organic phase was neutralized by washing with a dilute solution of sodium carbonate, then with distilled water and finally dried over anhydrous magnesium sulfate. After filtration,... 

Cyclohexene-1 -methanol undergoes smooth Williamson etherification with a,co-dibromoalkanes in the presence of base and a phase transfer catalyst. The resulting biscyclohexenyl ethers, XXIIa-e, were subsequently treated with m-chloroperoxybenzoic acid to give the desired diepoxide monomers, XXIIIa-e. Table 3 gives the characteristics of these monomers. 

Using a protocol for tandem carbonylation and cycloisomerization, Mandai et al.83 were able to synthesize cyclopentene and cyclohexene derivatives in high yield, including fused and 5/>/>0-bicycles (Scheme 25). The cyclohexene Alder-ene products were not isolable methanol addition across the exocyclic double bond (in MeOH/ toluene solvent) and olefin migration (in BuOH/toluene solvent) were observed. The mechanism of methanol addition under the mild reaction conditions is unknown. In contrast to many of the other Pd conditions developed for the Alder-ene reaction, Mandai found phosphine ligands essential additionally, bidentate ligands were more effective than triphenylphosphine.
