In many respects, this is the kernel of this book. For years it has not been too clear how one could consistently account for the wide variety of transition-metal chemistry in a way that does not conflict with the equally varied phenomena of spectroscopy and magnetochemistry that are so well rationalized by ligand-field theory. There is a tendency - psychologically quite natural, no doubt - for those interested in synthetic and mainstream chemistry not to look too closely at theory and physical properties, and, of course, vice versa. However, there has always been the need, surely, to build a logical synthesis of, or bridge between, these two aspects of the same subject. We hope that our presentation in this book goes some way towards providing that overview. 

AT-Heteroaryl ring systems are well-known as bridging functions between transition metal centers [12, 40, 41]. The pyridyl substituent is one of the representative examples of such systems that has been a widely used ligand in transition metal coordination chemistry [42]. However, the interest in group 13 metal chemistry of these ligands is of recent interest. Stalke et al. [43] have reported the synthesis and structure of the aluminum adduct Me3Al(/r-Py)PPy2 10.

By 1977-78, the initial growth period of metal atom synthesis in organometallic chemistry was coming to an end. Various factors contributed to this slow-down. One was that a lot of the more...

They are very effective ways of retaining specific metal ions in a nonexchanging site. In effect, each M.porphyrin is a new element , different from the parent metal ion compare free Mg2+ with chlorophyll, and its organic part is different for each metal ion (see (5) below). Thus a metal element becomes like S or P in non-exchanging selectivity similar in a sense to that of organo-metallic chemistry (see Section 2.16). The concentrations of the complexes has then separate controls of synthesis based on novel transcription factors. 

This chapter has discussed the transition metal-catalyzed synthesis of allenes. Because allenes have attracted considerable attention as useful synthons for synthetic organic chemistry, effective synthetic methods for their preparation are desirable. Some recent reports have demonstrated the potential usefulness of optically active axially chiral allenes as chiral synthons however, methods for supplying the enantiomerically enriched allenes are still limited. Apparently, transition metal-catalyzed reactions can provide solutions to these problems. From the economics point of view, the enantioselective synthesis of axially chiral allenes from achiral precursors using catalytic amounts of chiral transition metal catalysts is especially attractive. Considering these facts, further novel metal-catalyzed reactions for the preparation of allenes will certainly be developed in the future.
