Dihydride zirconocene

A large number of dihydride zirconocene complexes have been prepared, as for example [CpjZrHJi [51, 52], ]CpCp ZrH2]2 [53], [Cp 2ZrH2] [54], [(11 -1,3-... 

Dihydrides metallocenes can react with (jj -diarylketone) zirconocene dimers to yield dimetaUic compounds (17). These systems contain a dimetaUabicyclic framework in which... 

A convenient method for the synthesis of zirconocene hydrido chloride, isobutyl hydride, and dihydride complexes has been developed using the BuTi reagent.452 Thus, the reaction of Cp Cp"ZrCl2 with BuTi reagent gives... 

Binuclear cationic zirconocene hydrides can be prepared directly from the zirconocene dihydride precursor. Thus, the reaction of the zirconocene dihydride 626 with a trityl borate salt produces the binuclear hydrido complexes 627457 (Scheme 141). The synthesis of 627 may be accompanied by the formation of cationic zirconocene hydrides of higher nuclearity. For example, cationic trinuclear hydrido complex 628 was also isolated during the recrystallization...
