Isomerisierung der Bis(triphenylphosphin)platin(0)-Komplexe von Bicyclo[4.2.1]non-1-en und Bicyclo[4.2.1]non-1(8)-en

Isomerization of the Bis(triphenylphosphine)platin(0) Complexes of Bicyclo[4.2.1]non-1-ene and Bicyclo[4.2.1]non-1(8)-ene Isomrisation of the Bredt-Olefins 3 and 7 as the bis (triphenylphosphine)-Pt(0) complexes 1 and 8 , respectively, has been observed. The bridgehead-olefin 3 as well as the bicyclic olefins 4 , 5 and 6 have also been isomerized with catalytical amounts of (ethylene)bis(triphenylphosphine)platinum(0) ( 2 ).
