The synthesis of the tellurium analogues of (24) and (25) requires a different approach, since it is not possible to prepare the necessary amido precursors in significant yields by telluration of [ BuN(H)P( U-N Bu)2PN(H) Bu]. However, the prior hthiation of this P(III)/P(III) system to give (7) followed by reaction with elemental tellurium generates the dianion (24, E = Te) as its dihthium salt (Eq. 5) [37] ... 

Two principle strategies have been employed for the synthesis of siloxide-containing molecular precursors. The first involves a silanolysis, or condensation, reaction of the Si - OH groups with a metal amido, alkyl, hahde, or alkoxide complex. The second method involves salt metathesis reactions of an alkali metal siloxide with a metal hahde. Much of our work has been focused on formation of tris(tert-butoxy)siloxide derivatives of the early transition metals and main group elements. The largely imexplored regions of the periodic table include the lanthanides and later transition metals.

Quatemized imidazolines with an amido moiety are suitable formulations for general oil and gas field applications. The synthesis of such compounds is detailed in the literature [1218]. For aqueous systems that contain sulfide compounds, a mixture has been described [262] that consists of an aqueous solution of an alcohol such as diethylene glycol monobutyl ether, butyl cellosolve, additional orthophosphoric acid, a fatty acid (from tall oil), substituted imidazoline, an ethoxylated fatty diamine (polyamines such as ethylenediamine, diethylenetriamine, etc.), and a molybdate compound. 

Finally, the DCC procedure was applied to the synthesis of the 2-acet-amido-2-deoxy-D-galactose37,38 (30), D-galactose38 (31), and D-man-nose38 (32) analogs of 11. 

The complex cp Ir[OC(Ph) =NNCOPh], (195), was obtained from the reactions of cp IrNtBu or [cp Ir(/i-OH)3Ircp ]OH with (PhCONH)2. 0 X-ray structural analysis suggests that the product species should be considered as an electronically unsaturated Ir111, 16-electron complex with normal oxide and amido bonds. The synthesis of the chiral half-sandwich complexes (196) and (197) has been detailed.361... 

A first terminal imido complex of nickel (121) was prepared according to Equation (3).468 The synthesis goes via the Ni11 amido compound (122) and uses the steric bulk of the arylimido group for stabilization. The Ni11 center in (121) is planar and three-coordinate. Reaction of (121) with CO or benzyl isocyanide leads to formal nitrene transfer with formation of (124) and (125), respectively. Further reaction with CO liberates the isocyanate and carbodiimide (Equation (4)). 69... 

Other lignins can be reacted with this chemistry. Table 7 shows synthesis data for the preparation of poly(lignin-g-(1-amido-ethylene)) from several different lignins. Sample 1 is a kraft pine lignin grafted in a reaction coinitiated with sodium chloride.
