Efficient Synthesis of Dithienogermole (DTG) Derivatives via Olefin Cross-Metathesis

Abstract

4,4′-Bis-(4-pentenyl)-dithieno[3,2-<i>b</i>:2′,3′-<i>d</i>]germole was synthesized as a functional building block for the efficient preparation of dithienogermole (DTG) derivatives with varying alkyl chain lengths and pendant functionalities in excellent yields. These derivatives were efficiently isolated via olefin cross-metathesis followed by hydrogenation
