Lammertsma et al. on cover Angewandte Chemie
The background of the cover picture shows John Montagu (1718-1792), 4th Earl of Sandwich and 1st Lord of the Admiralty, who certainly would not have dreamt that an important class of organometallic compounds, sandwich complexes, would bear his name one day. The synthesis of the 16-electron Fe(P2C2tBu2)2 shows that sandwich complexes are still topical objects of research.
In the same issue on page 3108 ff. the Lammertsma group reported their findings on the P2-analogue of the Dötz intermediate and the implications of replacing carbon for phosphorus in metal carbenes and metathesis intermediates.
