Detailed Dynamics of the Photodissociation of Cyclobutane

The Journal of Physical Chemistry A, 2007
Semiclassical electron-radiation-ion dynamics simulations are reported for the photodissociation of cyclobutane into two molecules of ethylene. The results clearly show the formation of the tetramethylene intermediate diradical, with dissociation completed in approximately 400 fs.

A Cyclobutane possessing Hypotensive Activity

Nature, 1964
A NUMBER of non-quaternary bases have been found to possess ganglionic blocking and hypotensive properties1–5. In investigating the pharmacological properties of a new series of cyclobutanes6, one of them, 3-dimethylamino-2,2,4,4-tetramethyl-cyclobutanol, was found to exhibit a lowering activity of the blood pressure of long duration.

Cyclobutanes from Combretum albopunctatum

Phytochemistry, 2004
A dichloromethane extract of the aerial parts of Combretum albopunctatum Suesseng afforded five phenolic compounds-three known flavonoids and two novel cyclobutane chalcone dimers. The chemical structures were determined by standard spectroscopic techniques and the structure and relative stereochemistry of one chalcone dimer, rel-(1 alpha,2 beta)-di-(2,
