Zirconium complexes of a tacn-derived amido ligand and ring-opening to form a new diamido-amino pincer
Abstract
The tribenzyl complex
(Pri2tacn)Zr(CH2Ph)3 eliminates
toluene upon heating with concomitant ring-opening of the anionic ancillary
macrocycle to yield [CH2CHNCH2-
CH2N(Pri)CH2CH2NPri
]Zr(CH2Ph)2; the latter features a new class of
dianionic pincer ligand.
