ABSTRACT This article summarizes the knowledge about 5- Palladatricyclo [4.1.0.02,4] heptanes. Their synthesis by the only route yet known, the oxidative cyclization of two cyctopropenes at a Pd(0) center is discussed. Special attention is devoted to the aspect of stereoselectivity and the structural features of this chiral and strained metallacycloalkane. Furthermore the reactivity of the 5-palladatricyclo [4.1.0.02,4] heptanes is described and compared with the reactivity of the related palladoles. |
