Ketones are efficiently deoxygenated in the presence of silane using highly electrophilic phosphonium cation (EPC) salts as catalysts, thus affording the corresponding alkane and siloxane. The influence of distinct substitution patterns on the catalytic effectiveness of several EPCs was evaluated. The deoxygenation mechanism was probed by DFT methods.
Novel Rearrangement of 5,6-Disubstituted Bicyclooctan-2-ones with AlCl3. Application to Total Synthesis of (+/-)-5-Oxosilphiperfol-6-ene and (+/-)-Silphiperfol-6-ene

The acid-catalyzed rearrangement of bi- and tricyclic cyclobutyl ketones 8-20 having a bicyclooctan-2-one moiety with AlCl3 was studied to elucidate the scope and limitations of the novel rearrangement by which the tricyclic ketone 1 gave the angul
ACID CATALYZED RING CONTRACTIONS IN ENDO-2,8-TRIMETHYLENE-CIS-BICYCLOOCTYL CATIONS TO METHYLPERHYDROTRIQUINACENES. ONE OF THE METHYL EXTRUSION PROCESSES IN THE TRICYCLOUNDECANE REARRANGEMENT

Sulfuric acid catalyzed ring contractions with extrusion of a methyl group were examined for alcohol and olefin derivatives (28-31) of endo-2,8-trimethylene-cis-bicyclooctane (11), which was one of the two possible progenitors, among altogether 69
