The chemistry of the dicarbonyl(7 -cyclopentadienyl)nitrosyl and the chloro-(i7 -cyclopentadienyl)dinitrosyl complexes of chromium, molybdenum, and tungsten [i.e., fT -CsHs)M(CO)j(NO)] and [(i7 -CsHs)M(NO)2Cl] has not been studied extensively, partly because of the various difficulties associated with their preparation. The procedures described below are of general applicability to all three metals and lead to the desired compounds in high yields. The carbonyl nitrosyl complexes are the synthetic precursors of the chloro nitrosyl complexes and so their preparation is described first.

There are a number of different types of polymers that contain metal carbonyl complexes attached to polymer backbones and side chains. In the 1970s, Pittman and coworkers reported the synthesis and polymerization of a wide range of vinyl monomers containing transition-metal-coordinated cyclopentadienyl rings. Polymer 21 is an example of a copolymer containing chromium and manganese complexes in the side chain. Another class... 

Almost all stable olefin complexes of the chromium group metals are derivatives of carbonyl and cyclopentadienyl compounds (Table 6.13). Most of the metal alkene compounds may be classified as one of the following groups ... 

Many allyl complexes of chromium group elements are known, particularly those possessing mixed cyclopentadienyl and carbonyl ligands. Chromium forms compounds of the composition [Cr(allyl)3], while molybdenum and tungsten, like metals of the second and third transition metal series of the preceding groups, coordinate a larger...
