THE EFFECTS OF ALLYL ETHERS UPON RADICAL POLYMERIZATIONS.

, 2001
Three allyl ethers, viz. the ethyl, 2-hydroxyethyl and phenyl compounds, have been examined as additives in radical polymerizations of styrene (STY), methyl methacrylate (MMA) and acrylonitrile (ACN) at 60°C using azobisisobutyronitrile as initiator.

Dielectric constant-temperature relationship in some chlorinated phenyl ethers

, 1958
Dielectric liquids play an important role in the transmission, distribution, and use of electrical energy. A liquid is arbitrarily classed as a dielectric if its volume resistivity is 10(10) ohm-centimeters or greater.

1,2-Addition of dimethyl(phenyl)silyllithium to cyclic [alpha],[beta]-unsaturated ketones and regiospecific generation of cyclic silyl enol ethers through brook rearrangement of the 1,2-addition products

, 1990
A highly convenient two-step sequence for the regiospecific synthesis of cyclic silyl enol ethers has been developed involving the 1,2-addition of dimethyl(phenyl)silyllithium to cyclic [alpha],[beta]-unsaturated ketones followed by the treatment of the ...

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

Angewandte Chemie International Edition, EarlyView.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

The synthesis and characterization of phosphine functionalized crown ethers by use of spectroscopic and x-ray methods

, 1995
The phosphine(III) crown ethers, [4'-(N-phenylaza-15crown-5)]3P (1), [4'-(N-phenylaza-l8-crown-6)]3P (2), [4'-(Naza-18-crown-6)]2-Ph-P (3), and [4'-(benzo-15-crown-5)]3P (4) were synthesized by using an electrophilic bromination of the crown phenyl ring (

Photogenerated Oxetanes as a Gateway to Uphill Cyclopropanation

Angewandte Chemie International Edition, EarlyView.
An atom‐economical route to densely functionalized cyclopropanes from furans and photochemically activated aldehydes is enabled by a unique oxetane‐to‐cyclopropane rearrangement. These cyclopropanes can be used to access complex bioactive scaffolds and serve as a platform for asymmetric cyclopropane synthesis.
