- ansa-bis(1-boratabenzene) zirconium (IV) complexes with short carbon bridges to boron
-
The reaction of 1,1-dibutyl-1-stannacyclohexa-2,5-diene (8) with 1,2-bis(dichloroboryl)benzene 9 affords exchange product 10, which on deprotonation followed by reaction with ZrCl4 gives the very labile o-phenylene-bridged bis(1-boratabenzene)zirconium dichloride 6. A similar reaction sequence from 8 and 1,1-bis(dichloroboryl)-2-methyl-1-propene 11 affords the 1,1-isobutenyl-bridged bis(1-boratabenzene)zirconium dichloride 7. The X-ray structure of 7 is described.
