C4H8 An alicyclic hydrocarbon, boiling point 11°C; synthesized as a condensable gas; used in organic synthesis. Also known as tetramethylene.

Cyclobutane

 

(also tetramethylene), an alicyclic hydrocarbon; a colorless gas, with a weak odor, a boiling point of 12.9°C, and a density of 0.703 g/cm3 (at 0°C).

Cyclobutane is insoluble in water but is soluble in alcohol, acetone, and ether. It has all the chemical properties characteristic of cycloparaffins. It may be obtained from 1,4-dibromo butane and by other methods. Octafluorocyclobutane, C4F8, produced by the dimerization of tetrafluoroethylene is used in industry as a freon.

His design employs either polyesters (more sustainable due to access to bio-based raw materials) or poly-imides (for high-temperature applications) that are functionalized with cyclobutane substrates through the photochemistry of maleic anhydrides, which undergo a [2[Plus]2] cycloaddition reaction to form cyclobutanes when exposed to one wavelength of light and the reverse when exposed to another.
