Control of Carbene Reactivity by Crystals. A Highly Selective 1,2-H Shift in the Solid-to-Solid Reaction of 1-(4‘-Biphenylyl)-2-phenyldiazopropane to (Z)-1-(4‘-Biphenylyl)-2-phenylpropene

open access: yes, 2016
Ruby red polycrystalline samples of 1-(4‘-biphenylyl)-2-phenyldiazopropane (1a) efficiently transform into colorless (Z)-1-(4‘-biphenylyl)-2-phenylpropene [(Z)-3a] in up to 96% yield in a highly selective photochemical solid-to-solid reaction.

A VUV Photoionization Study of the Combustion-Relevant Reaction of the Phenyl Radical (C6H5) with Propylene (C3H6) in a High Temperature Chemical Reactor [PDF]

open access: yes, 2012
We studied the reaction of phenyl radicals (C6H5) with propylene (C3H6) exploiting a high temperature chemical reactor under combustion-like conditions (300 Torr, 1,200-1,500 K). The reaction products were probed in a supersonic beam by utilizing tunable

SUBSTRATE ENANTIOSELECTIVITY IN THE RABBIT LIVER MICROSOMAL EPOXIDE HYDROLASE CATALYZED-HYDROLYSIS OF TRANS AND CIS 1-PHENYLPROPENE OXIDES - A COMPARISON WITH STYRENE OXIDE

open access: yes, 1993
A preferential consumption of the (IS,2S) enantiomer of (+/-)-trans-1-phenylpropene oxide (3) and of the (1R,2S) enantiomer of cis-1-phenylpropene oxide (5) is observed during the rabbit liver mEH catalyzed hydrolysis of these epoxides.

Assessing the feasibility of a one-pot, tandem olefin metathesis and isomerization sequence to synthesize conjugated aromatic olefins [PDF]

open access: yes, 2016
The synthesis of substituted phenylpropene dimers using a one-pot, tandem olefin metathesis and isomerization sequence has been studied. This sequence relies on the facilitated, in-situ conversion of a ruthenium carbene species (Ru=C) to a ruthenium ...

Towards Bio‐Based Benzoxazines (2015–2025): A Critical Review of Renewable Building Blocks, Formaldehyde‐Free Aldehydes, and ECHA Hazard Landscape

open access: yesPolymers for Advanced Technologies, Volume 37, Issue 8, August 2026.
ABSTRACT This review provides a critical overview of research on fully bio‐based benzoxazines over the period 2015–2025. A bibliometric analysis based on the Web of Science database is used to map how the field has evolved and to identify the renewable building blocks that have been most widely adopted.

Structure and biosynthesis of the phenylpropenes.

open access: yes, 2013
(A) Phenylpropene diversity. The basic skeleton of an allyl phenylpropene is shown, along with the numbering of the carbon atoms used in this manuscript. The iso phenylpropenes differ in the position of the double bond (C7 = C8) in the propene side group.
