Adamantyl phenyl ketone

Treatment of hydrazones derived from 1-adamantyl phenyl ketone, pivalophe-none and benzophenone with sulfur monochloride gave pentathianes 232 and hexathianes 233 along with the corresponding ketones and thioketones as the main products (1997H255 Scheme 124). 

The treatment of hydrazones derived from l-adamantyl(phenyl)ketone, pivalophenone, and benzophenone with S2C12 gave hexathiepanes 131 (Figure 31) along with other products as tetra- and pentathianes (1997H255). 

In Schemes 30 to 35, products of the irradiation of several systems containing carbonyl chromophores (oxoamides, adamantyl phenyl ketones, a-mesitylaceto-phenones, and a-benzonorbomyl aceotophenones) are presented [282,301-303], Primary photoreaction in every one of these cases is intramolecular 7- or 8-hydrogen abstraction. In the majority of these cases the final products of interest are cyclobutanols (Scheme 36). Of the forty compounds examined, the de of the cyclobutanols or cyclopentanols in solution is less than 15%. On the other hand,...
