Triphosgene and DMAP as Mild Reagents for Chemoselective Dehydration of Tertiary Alcohols

The utility of triphosgene and DMAP as mild reagents for chemoselective dehydration of tertiary alcohols is reported. Performed in dichloromethane at room temperature, this reaction is readily tolerated by a broad scope of substrates, yielding alkenes preferentially with the (E)-geometry. While formation of the Hofmann products is generally favored, a dramatic change in alkene selectivity toward the Zaitzev products is observed when the reaction is carried out in dichloroethane at reflux.

Steric Effects in Photochemical Cycloadditions of 9-Phenanthrenecarboxylates

Efficiency of photochemical intramolecular and intermolecular cycloadditoin of 9-phenanthrenecarboxylate-anethole systems is dependent on the structure of anethole moiety.Reduction in reactivity of the anethole moiety by steric effects is explained in terms of decrease in coefficients of frontier orbitals on the double bond due to twisting of the anisyl moiety.
