When aldicarb in acetonitrile was irradiated by UV light (X = 254 nm), methylamine, dimethyl disulfide, tetramethylsuccinonitrile, and l-(methylthio)-2,3-dicyano-2,3-dimethylbutane were produced. Minor amounts of WW-dimethylurea also formed. The same products were formed when the photolyses were carried out in the presence of acetophenone, benzophenone, or benzonitrile (Freeman and McCarthy, 1984).

N-Alkylnitrilium salts, prepared from benzonitriles and SbQs, acylate activated aromatic compounds under mild conditions. The resulting benzophenone imines can be cyclised and hydrolysed providing a good route to substituted xanthones (Scheme 34) <99 JOC4050>. 

It has been shown that the benzophenone sensitized decomposition of benzoyl peroxide is due in part to formation of the benzophenone ketyl radical, which induces decomposition.98,99 Hydrocarbon sensitized peroxide decomposition is discussed in Section IV.A.4. The formation of benzonitrile from the benzophenone sensitized irradiation of benzalazine, which was originally attributed to hydrogen abstraction by benzophenone,100 actually results from a photooxidation.101... 

Numerous studies involving similar amido derivatives of metals such as Ti (e.g. heterometallic cross-coupling of benzonitrile with carbon dioxide, pyridine, and benzophenone with mixed [Ti N(Bu )Ar 3] and [Mo N(Bu )Ar 3] systems), V (e.g. denitrogenation of a vanadium nitride by carbon disulfide and dioxide), Nb (e.g. the... 

In one of the earliest reports on ortho photocycloaddition, in which the reaction of benzonitrile with 2-methylbut-2-ene is described, a diradical (triplet) intermediate was proposed [73], The structure of the product corresponds to the most stable of the four possible diradical intermediates. When benzophenone was added as a sensitizer in an attempt to increase the yield of the photoadduct, only 0.05% of ortho adduct was isolated along with 54% of an oxetane formed by the addition of benzophenone to 2-methylbut-2-ene. In the absence of benzophenone, the ortho adduct was isolated in 63% yield. It is, however, thermally as well as photochemically unstable and reverts to starting materials, supposedly also via a biradical. The authors propose that benzophenone catalyzes bond cleavage of the adduct more efficiently than ortho addition and this would account for the low yield of photoadduct in the presence of benzophenone. From these experiments, no conclusion about the identity of the reactive excited state can be drawn.
