The mass spectra of Tr-cyclopentadienyl metal compounds usually give abundant parent ions and show varying degrees of ring fragmentation. Despite this, however, processes are observed corresponding to the extrusion of the metal ion (231) or neutral metal atom (232), e.g.,... 

Still other 7r-cyclopentadienyl-metal compounds have been shown to undergo acylation. The successful acylation of cyclopentadienylmanganese tricarbonyl has opened up yet another interesting aromatic-type system for exploration (9, 10, 11, 13, 20, 45, 99). An example of this type concerns the benzoylation of methyl-cyclopen tadienylmanganese tricarbonyl (XII) (10, 45). Both l-methyl-2-ben-zoylcyclopentadienylmanganese tricarbonyl (XIII) and the corresponding 1,3-isomer (XIV) are readily obtained.

Fortunately, the area of organotransition metal chemistry dealing with TT-cyclopentadienyl-metal compounds is well reviewed. Two comprehensive reviews covering the literature until 1959 have been written by Wilkinson and Cotton 245) and by Fischer and Fritz 87). Several more recent reviews have been written by Birmingham 12j 13) and by Rausch 200j 202). The topic of metallocenes has been extensively reviewed by Rausch 199j 200j 202, 204), Plesske 196), and Little 160). The most recent review of metallocene chemistry is a two volume series by Rosenblum, the first volume of which has recently been published 217).
