Preparation and X-ray structure of 8,9,19,20-tetra hydrodinaphtho[1′,8′′jk; 1,8-bc][1,5,9,13]tetraselenacyclohexadecine, and its novel ring contraction in concentrated sulfuric acid
Abstract
The novel title compound 1 has been synthesized; upon hydrolysis in sulfuric acid it gave ringcontracted products naphtho[1,8-bc]-1,5-diselenocin and its selenoxide.
