“…A new work on iron porphyrins, ferrocenes and related iron compounds has been summarized; among the topics discussed are organic reactions of selected π-complexes [ 545 ], stereochemistry of metallocenes [ 546 ] and the recent chemistry of ferrocene compounds [ 547 , 548 ]. Other topics of recent interest are: bridged ferrocenes [ 549 ], reaction of the isodicyclopentadiene anion with Fe(II)(acac) 2 (Py) 2 (to yield ferrocene derivatives) [ 550 ], preparation of iron-polyarene sandwich compounds [ 551 ], and crystal structure of [ 2 ]metacyclo[ 2 ](1,1′) ferrocenophane [ 552 ].…”
