“…The nitroxide radical (2,2,6,6-tetramethyl-1-piperidinyloxy) TEMPO was purchased from Aldrich and sublimed prior to use. TpTiCl 3 and Tp*TiCl 3 were prepared by reaction of KTp or KTp* with TiCl 4 using modified literature procedures [4,5].…”

“…1). Although this compound was easily reduced by Zn, it subsequently formed an insoluble purple precipitate typically associated with over‐reduction 50, 51. Thus, because of the lack of sufficient Ti(III) species throughout the polymerization, when M n increases from 30,000 to 50,000 it is associated with a high intercept at low conversion and a very broad distribution.…”

These eye findings, as complications of AN, have not been described in the literature. With careful protective measures, initiation of nutritional rehabilitation, and intensively monitored early refeeding, these patients' ocular abnormalities and associated symptoms resolved completely. Recognition of this pathology and appropriate management can prevent long-term morbidity in the form of permanent loss of visual acuity due to corneal abrasions and improve the outcomes for these patients with severe AN.

Treatment of the tris(pyrazolyl)borate metal triamides Tp'M(NMe(2))(3), where Tp' = (C(3)H(3)N(2))(3)BH (Tp) or (3,5-Me(2)C(3)HN(2))(3)BH (Tp*) and M = Ti, Zr and Hf, with the Brønsted acidic Lewis adduct (C(6)F(5))(3)B·NH(3) in toluene solution leads to the formation of Tp'M(NMe(2))(2){NH(2)B(C(6)F(5))(3)} complexes. The exception to this was the attempted preparation of Tp*Ti(NMe(2))(2){NH(2)B(C(6)F(5))(3)} which was unsuccessful. Where Tp' = Tp and M = Ti and Zr and where Tp' = Tp* and M = Zr the complexes have been characterized by single crystal X-ray diffraction methods, revealing the first examples of octahedral amidoborane complexes of the group 4 metals. Attempts to drive the reactions to completion resulted in competing preferential hydrolysis of the amidoborane group, regenerating (C(6)F(5))(3)B·NH(3).
