Abstract

Zinn, nein danke! Thiolester konnten mit der im Schema gezeigten zinnfreien Radikalcarbonylierung synthetisiert werden (V-40=Initiator). Dieser Ansatz lässt sich auf sequenzielle Radikalreaktionen ausdehnen, die Cyclisierung, Carbonylierung und das Abfangen von Acylradikalen durch Phenylbenzolthiosulfonat umfassen.
