Tungsten carbon dioxide complex

As in the monoene chapter, the stoichiometric and catalytic reactions of dienes with carbon dioxide will be discussed in the sequence of the transition metal applied. It is remarkable, that almost the same metals are described both in monoene and in diene/C02 chemistry. Two differences, however, should be stressed In the presence of molybdenum and tungsten complexes no interactions between dienes and carbon dioxide are reported (until now). On the other hand, palladium is a much more versatile and effective metal in diene/C02 than in monoene/CO chemistry.
