Titanous amide

A more recent patent describes the production of titanyl nitrate by electrolysis of titanium tetrachloride or titanyl chloride (37). Other titanium nitrogen compounds that have been described include titanous amide [15190-25-9] Ti(NH2)3, titanic amide [15792-80-0] Ti(NH)2, and various products in which amines have reacted with titanium tetrachloride (38). 

In the presence of alkoxides or amides, e.g., liberated during the preparation, ate complexes are reversibly formed and may modify the reactivity of the a-titanated 2-alkenyl carbamates17. 

Electrostatic potential surfaces of Gly-Gly and the fluoroolefin isostere created with B3LYP/6-31G by using Titan 1.0.5 (Fig. 5) illustrates that reduced polarization of the fluoroolefin relative to the amide bond. The original postulates described above were confirmed in independent findings from two groups [14,44] (Fig. 5). 

A comprehensive group of polyesters contains hindered piperidine or piperazine (HALS) moieties. Most of these stabilizers were prepared under transesterification conditions, using tetraalkyl titanates, lithium amide or sodium alkoxide as catalysts. Terminal HALS group was built in under these conditions into a polyether-polyester. Polyester 145 was prepared from a reactive diester derived from piperazinedione and fljco-alkylidenediol (n = 2-15) [188], A similar system contains 2,2,6,6-tetramethylpiperidine moiety [189]. 

Reductive amination is historically defined as the combination of a Brpnsted acid, a ketone, an amine, and a coexisting reductant. The recent evolution of titanium (IV) alkoxides, as mild Lewis acid replacements for Brpnsted acids, owes its genesis to a clever modification of titanium amide chemistry demonstrated by Mattson et al. in 1990. By prestirring a ketone, amine, and Ti(OiPr)4 (neat), followed by the addition of EtOH and NaBH3CN, the desired reductive amination product was afforded (Scheme 8.8). The same authors suggested that these reductive aminations proceeded through a hemiaminal titanate intermediate, based on IR spectroscopy before addition of the reductant.

A reducing agent. Reacts violently with strong oxidizers and many other materials. Reacts with water producing butanol and titanium dioxide, and possibly, toxic or flammable fumes. Incompatible with acids sulfuric acid, nitric acid bases, amines, amides. 

It was found that aromatic imide and amide forming components with a functionality of more than two yield products that are soluble in cresol." Additives for wire enamels are phenolic resins, melamine resins, fluori-nated compounds, or, benzyl alcohol. Crosslinking catalysts are zinc oc-toate, cadmium octoate, or titanates, such as tetrabutyl titanate. Extenders are xylene, toluene, ethylbenzene, or cumene, and commercial available similar compounds.
