At 170 °C, 1,1'-bis(3,4-dimethylphospholyl)ferrocene (7) isomerises through the corresponding 2H-phospholes that are trapped by diphenylacetylene to give the 1,1'-ferrocenylene-bridged bis–1-phosphanorbornadiene (6). After resolution with a optically pure palladium complex, (R,R)- and (S,S)-(6) are tested in the asymmetric hydrogenation of a dehydroaminoacid, hydroformylation of styrene, and allylation of sodium malonate.
