Die Darstellung α,ω-bifunktioneller Ausgangsverbindungen sowie (Z)- und (E)-konfigurierter, ungesättigter Synthesebausteine, die man mittels Wittig-Reaktion, Michael-Addition, Acetylen-synthese oder Crombie-Reaktion erhält, wird beschrieben. Diese Verbindungen werden im Rahmen eines „Baukastensystems” zur Synthese bisolefinischer Sexualpheromone benötigt.
Organofluorosilicates in Organic Synthesis. XVI. Synthesis of Organopentafluorosilicates<i>via</i>the Diels-Alder, Ene, and Friedel-Crafts Reaction. Their Transformations to Organic Halides and Alcohols
Described herein are several representative examples of cleavage reactions of otherwise hardly accessible organopentafluorosilicates which are obtainable via the Diels-Alder reaction, ene reaction, and the Friedel-Crafts reaction of vinyl-, ethynyl-, or allyl-trichlorosilanes. The Diels-Alder reaction between vinyltrichlorosilane and o-xylylene generated in situ by debromination of α,α′-dibromo-o-xylene
