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.
