2-Methoxy-4-propenylphenol

A second hydroxyl or methoxyl substituent is often present 2-methoxy-4-allylphenol and 2-methoxy-4-propenylphenol are the most important compounds belonging to this category.

The combination of GC with FTIR and MS detection has been used for a variety of applications [138-142]. In all of these the GC effluent is spht through a tee and each branch goes to one of the two detectors. Examples include a sample from suspected clandestine use of a chemical laboratory showed phenyl-2-propanone and other compounds indicative of methamphetamine production, the concentration of benzene, toluene, the xylene isomers, and 1,2,4-trimethylbenzene in a gasoline, the trace contaminants in solvents used in semiconductor manufacture, the three flavor essence isomers eugenol, and ds-and trans- isoeugenol (4-allyl-2-methoxy-phenol and ds- and trans- 2-methoxy-4-propenylphenol), and the components in a perfume sample. In the last of these, the sample was previously ran by GC-AED with C, H, O, and N detection to augment the other two types of detectors. 

The possibility of converting lignin, a natural polyphenol, to vanillin by Co(NMesalpr) catalyzed oxidation [118] has been demonstrated. A model system suitable for mechanistic studies is the oxidation of isoeugenol (2-methoxy-4-propenylphenol) to vanillin (2-methoxy-4-formylphenol) [119]. The superoxo species derived from... 

Synthesis of 2-methoxy-4-propenylphenyl methylcarbamate, 11. Into a 500 ml one-necked round-bottomed flask, 10.0 g (0.0609 mole) of 9 (2-methoxy-4-propenylphenol) was dissolved in 200 ml of ligroin (b.p. 20-40 C). To this solution, 6.94 g (2 x 0.0609 mole) of methyl isocyanate and 200 pml of triethylamine were added. The mixture was stirred by a magnetic stirrer and heated by means of a heating mantle to the reflux temperature for 57 hours.
