Abstract
The addition reaction of allene in the presence of Rh(diphos)(h6-BPh4) has been investigated and the conditions leading to the head to tail (H-T) or to the head to head (H-H) coupling have been studied. Moreover, Co-condensation of allene with carbon dioxide has been demonstrated to require more drastic conditions than the allene addition. The influence of solvents and temperature on the above mentioned reactions have been investigated and the role of amines in the trasformtion of the catalyst has been defined.File in questo prodotto:
