DSC analysis of a mixture of PBT cyclic oligomers containing the stannox-ane 3 showed only the melting endotherm (AH = 68 J/g), with no exotherm evident. Apparently, polymerization starts as the cyclics melt. Cooling showed the crystallization of the polymer, while the second heating stage displayed only the melting point of the PBT polymer at 213 °C (A H = 54 J/g) the polymer had an Mw of 117 000, and was 97 % polymerized (from GPC analysis). 

The nickel(II) complexes of the closely related macrocycle, tetra-TV-methyl-14-ane-N4 (tmc), can adopt the same set of isomers. It has been noted that the isomer observed depends on whether nickel(II) is four-, five- or six-coordinate[13]. Molecular mechanics modeling of this system and prediction of each of the structures allowed an analysis of the specific interactions between axial ligands and the macrocycle to be carried out 141. In this way a possible explanation for the experimental observations was arrived at. Specifically, it was concluded that the interactions between the methyl substituents on the ring and any axial ligands control the stabilities of the different isomerstl4]. 

Both Craig and Weiss (1971) and Bieri (1971) stress that analysis of the He anomalies must be based on comparison with those of Ne and Ar. Craig and Weiss (1971) made a formal analysis expressing each of AHe, ANe, and AAr as a linear sum of terms in AP, AT, and Aa (Section 4.1). A convenient graphical presentation (Figure 4.3) is the relation between AHe-ANe and ANe-AAr. Since pressure variations... 

The simplest example of a charged network based on trans-1,2-diaminocyclohex-ane is based on the carbon dioxide complex [51]. A forced carbonation of (R,R)-trans-1,2-diaminocyclohexane with carbon dioxide afforded the corresponding crystalline carbamate salt 41 (from ethanol-water), which was suitable for X-ray analysis (Scheme 18) [51,62],... 

Several polysilylene copolymers have also been examined by Si NMR. West and co-workers (3) report that phenylmethyldichlorosilane, when copolymerized with either dimethyldichlorosilane or methylhexyldichlorosil-ane, yields a copolymer with a blocklike structure. In contrast, we have observed that the copolymers of dimethyldichlorosilane with di-n-hexyldi-chlorosilane and n-propylmethyldichlorosilane with isopropylmethyldichlo-rosilane have random structures. These several examples indicate clearly that Si NMR spectra can provide a complete analysis of chain microstructure for the soluble polysilylene homopolymers and copolymers.

The cobalt(III) complex [Co(2,3-Me2[14]-l,3-diene-l,4,8,l l-N4)Br2] Br is six-coordinate and diamagnetic. Analysis of the visible spectrum (absorptions occur near 15.8 and 26.2 kK) leads to a value for Dq of 2630 cm" . The NMR spectrum in dimethyl sulfoxide shows a methyl singlet at 3.32 ppm. The infrared spectrum is very similar to that given for the nickel(II) complexes. A wide variety of cobalt(lll) complexes has been prepared by metathetical reactions on the dibromo and dichloro complexes. The imine functions can be hydrogenated, producing cobalt(III) complexes of 2,3-Me2 [14] ane-1,4,8,11-N4 or 2,3-Me2-[14]-l-ene-l,4,8,ll-N4. ... 

Capillary gas chromatography with optically active stationary phases became a well-established technique for stereochemical analysis after the pioneering work of Gil-Av and his associates in the mid-1960s (2). Thermal stability of the initially low-molecular-weight amino add and peptide derivatives was greatly improved after the introduction of chiral polysUox-anes by Frank, Nicholson, and Bayer (Chirasil-val [1], 1977) (3) and of... 

Results from weight-loss measurements were modeled.f Research indicates that the determination of water content by Karl Fischer analysis in effervescent tablets was possible after extraction with diox-ane. NaHCOs, which reacts with the Karl Fischer reagent, is insoluble in dioxane and does not interfere during the determination.
