TADDOLate as ligand in zirconium and hafnium chemistry was written by Datta, Simmi;Roesky, Peter W.. And the article was included in Zeitschrift fuer Anorganische und Allgemeine Chemie in 2006.Reference of 93379-49-8 This article mentions the following:
The enantiomeric pure TADDOLate complexes of the heavier Group 4 metals [(η5-C5H5)2M{(S,S)-TADDOLate}] (M = Zr, Hf) were prepared by treatment of (S,S)-TADDOL with 2.5 equiv of Bu Li followed by reaction with zirconocene and hafnocene dichloride, resp. The new complexes were characterized by standard anal./spectroscopic techniques and the solid-state structures of both compounds were established by single crystal x-ray diffraction. The title compounds are the 1st fully characterized TADDOLate complexes of Zr and Hf. In the experiment, the researchers used many compounds, for example, ((4S,5S)-2,2-dimethyl-1,3-dioxolane-4,5-diyl)bis(diphenylmethanol) (cas: 93379-49-8Reference of 93379-49-8).
((4S,5S)-2,2-dimethyl-1,3-dioxolane-4,5-diyl)bis(diphenylmethanol) (cas: 93379-49-8) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. 1,3-Benzodioxole can be synthesized from catechol with disubstituted halomethanes.Reference of 93379-49-8
