benzophenone

A benzophenone derived from alprazolam is also found in humans.

The benzophenone absorbs both the burning and tanning rays of the sun.

The reaction involved the use of hydroxylamine to convert benzophenone into an oxime.

The initial benzophenone compound was developed in West Germany in the 1950's.

For example, the conversion of benzophenone to its thione proceeds as follows:

The reaction depicted below describes the hydrogenation of benzophenone:

An example is its reaction with benzophenone:

It is a derivative of benzophenone.

Very dry solvents are obtained by refluxing over benzophenone and sodium metal prior to distillation.

Oxybenzone is a derivative of benzophenone, which can attack DNA when illuminated.

The benzophenone metabolite is essentially inactive.

Sodium reduces benzophenone to the deeply colored radical anion, diphenylketyl:

For the most important ketones, however, traditional nonsystematic names are still generally used, for example acetone and benzophenone.

Other products containing benzophenone also reduce exposure to UVA but not as effectively, studies have indicated.

A benzophenone is functionalised with a chromophore or group that can be easily converted to a chromophore at a later stage.

The high-strength polymer PEEK is prepared from derivatives of benzophenone.

The functionalised benzophenone is reacted with hydrazine hydrate and subsequently treatment with mercury oxide.

Sodium reduces benzophenone to the soluble ketyl radical, which reacts quickly with the water and oxygen dissolved in the solvent.

This intermediate is subsequently converted by a benzophenone 3'-hydroxylase, a cytochrome P450 monooxygenase, leading to the formation of 2,3',4,6-tetrahydroxybenzophenone.

The use of a benzophenone imine or silylamide can overcome this limitation, with subsequent hydrolysis furnishing the primary aniline.

(see Benzophenone).

Other symmetrical alkenes were prepared similarly, e.g. civetone from adamantanone and tetraphenylethylene from benzophenone.

Examples of cross-conjugation can be found in molecules such as benzophenone, divinylketones, p-quinones, dendralenes, radialenes, and fullerene.
