Bioherbicidal activity of terpenes and phenylpropenes against Echinochloa crus-galli
Journal of Environmental Science and Health, Part B, 2019This study was undertaken to evaluate the herbicidal activity of twelve natural compounds belonging to monoterpenes, phenylpropenes, and sesquiterpenes against Echinochloa crus-galli under laboratory and glasshouse conditions. Experiments were conducted to determine the impact of different concentrations (0.5, 1, 2, 4 and 8 mM) of these compounds on ...

ChemInform Abstract: Oxidative Photoaddition of N‐Nitrosodimethylamine to 1‐Phenylpropenes.
ChemInform, 1987AbstractIn the presence of HCl and under oxygen purging, the nitrosamine (V) photolytically adds to the arylpropenes (Ia), (Ic) to give threo‐ and erythro‐α‐amino nitrates (III) or (VIII) as the primary products which are reduced to yield the α‐amino alcohols (IV) or (IX), respectively.

Alkylation of p-cresol with 3-phenylpropen-1-ol-3
Bulletin of the Academy of Sciences, USSR Division of Chemical Science, 19641. The alkenylation of p-cresol with phenacyl alcohol in the presence of zinc chloride on aluminum oxide goes in the direction of the formation of 1-phenyl-3-(3-methyl-6-hydroxphenyl)propene-1 in 80% of theoretical yield. 2. The alkenylation of p-cresol with phenacyl alcohol proceeds with a larger yield than the allylation of p-cresol ...

Oxidative photoaddition of N‐nitrosodimethylamine to 1‐phenylpropenes
Recueil des Travaux Chimiques des Pays-Bas, 1986AbstractIn the presence of hydrochloric acid and under oxygen purging, N‐nitrosodimethylamine photolytically adds to 1‐arylpropenes regiospecifically to give erythro‐ and threo‐α‐amino nitrates as the primary products which can then be reduced, using lithium aluminium hydride, to give α‐amino alcohols or can undergo substitution reactions under ...

Adsorption geometry and core excitation spectra of three phenylpropene isomers on Cu(111)
The Journal of Chemical Physics, 2006Theoretical C 1s near edge x-ray absorption fine structure (NEXAFS) spectra for the C9H10 isomers trans-methylstyrene, α-methylstyrene, and allylbenzene in gas phase and adsorbed at Cu(111) surfaces have been obtained from density functional theory calculations where adsorbate geometries were determined by corresponding total energy optimizations.

A Clandestine Approach to the Synthesis of Phenyl-2-Propanone from Phenylpropenes
Journal of Forensic Sciences, 1984Abstract A number of published syntheses for the manufacture of controlled substances appear to be impractical for the average clandestine laboratory. A closer inspection of these syntheses may reveal modifications which greatly simplify their application. An excellent example of this is the preparation of phenyl-2-propanone (P-2-P) from
