Palladium-Catalyzed Cross-Coupling of Tertiary Cyclopropyl Carbagermatranes with Acyl Chlorides.

A simple method for the synthesis of cyclopropane compounds via cross-coupling reaction between tertiary cyclopropyl carbagermatranes and acyl chlorides was reported. Derivatives of acryloyl chloride and aliphatic acyl chloride also performed to be suitable substrates. This process can be used to introduce a wide range of functionalized cyclopropane groups and acyl groups directly.
