Abstract

Synthesis, Properties, and Reactions of Metal-Containing Heterocycles.Part 83. Synthesis of Differently Substituted Furans by Cobalt-Induced Cyclocotrimerization of a P=S Function with Acetylenedicarboxylic Dialkyl Esters.-Eight furans of type (III) are synthesized in 14-23% yields by the title reaction. A mechanism is proposed. -(LINDNER, E.; SCHLENKER, T.; FAWZI, R.; MAICHLE, C.; J. Organomet.
