SnO containing films the bulk materials and cast-side surfaces were characterized as dielectric in nature with loss and conduction. The air-side charging characteristics, on the other hand, were markedly different from the volume mode charging characteristics. No short term polarization occurred in the samples implying little or no direct contribution from the polymer matrix to the air-side electrical properties. Also, the air-side electrical resistivity of BTDA-ODA polyimide films at room temperature was reduced substantially for both cobalt chloride modified and tin chloride dihydrate modified samples (i.e. six orders of magnitude and eleven orders of magnitude, respectively). 

The ionic conductivities of the Sn-ferrierites and Sn-silicalites, prepared by treatment of H-zeolite with tin chloride dihydrate, were mentioned in literatrrre [93K1]. The ac birlk corrductivity of Sn-ferrierite is higher than that of H-ferrierite and depends on the water content - Fig. 57. The bulk conductivities are almost indeperrdeirt on temperature in the range between 298 and 388 K. 

A cousin to this reduction is one using stannous chloride (a.k.a. SnCb, a.k.a. Tin chloride) which is done exactly as the calcium one except that about lOOg of SnCb is used in place of the Mg or Ca and the addition occurs at room temperature and the solution is stirred for one hour rather than 15 minutes. Some very good reductions that operate almost exclusively at room temperature with no pressure and give almost 100% yields are to follow. The only reason Strike did not detail these methods is that some of the chemicals involved are a little less common than Strike is used to but all are available to the public. These alternatives include acetlylacetone and triethylamine [73], propanedithlol and trieth-ylamine [74], triphenylphosphine [75], NaBH4 with phase transfer catalyst [76], H2S and pyridine [77], and palladium hydrox-ide/carbon with hydrazine [78], stannous chloride dihydrate [85]. 

Stannous Chloride. Stannous chloride is available in two forms anhydrous stannous chloride, SnCl2, and stannous chloride dihydrate [10025-69-1], SnCl2 2H20, also called tin crystals or tin salts. These forms are sometimes used interchangeably however, where stabiUty, concentration, and adaptabihty are important, anhydrous stannous chloride is preferred. Even after long storage, changes in the stannous tin content of anhydrous stannous chloride are extremely low. Physical properties of the tin chlorides are Hsted in Table 1. 

Stannous Chloride Dihydrate. A white crystalline soHd, stannous chloride dihydrate is prepared either by treatment of granulated tin with hydrochloric acid followed by evaporation and crystallisation or by reduction of a stannic chloride solution with a cathode or tin metal followed by crystallisation. It is soluble in methanol, ethyl acetate, glacial acetic acid, sodium hydroxide solution, and dilute or concentrated hydrochloric acid. It is soluble in less than its own weight of water, but with much water it forms an insoluble basic salt. 

Tin(II) chloride solution. Dissolve lOg of tin(II) chloride dihydrate in 100mL of 1M hydrochloric acid. 

Dipping solution 1 Dissolve 2 g tin(II) chloride dihydrate in 20 ml hydrochloric acid (2S[Pg.62]

For formation of resin 3, the resin is washed in NMP (20ml/g of resin), filtered, and left solvated. Separately, tin(II) chloride dihydrate (approximately 40 equivalents with respect to resin-bound nitro groups) is dissolved in NMP with vigorous stirring, then the solution is added to the resin and mixed by nitrogen bubbling for 12 h at room temperature. The resin is filtered, washed, and left solvated prior to the next synthetic step.

Z,Z)-Bis[2-phenylethenyl] Ditellnrium2 6.4 g (50 mmol) tellurium, 42 g (750 mmol) potassium hydroxide. 22.6 g (100 mmol) tin(II) chloride dihydrate, 10,2 g(100 mmol) phenylacetylene, 20 ml toluene, 60 ml water, and 1.2 g Adogen 464 are vigorously stirred and kept at 80° to 97° for 7 h. The organic layer is separated and the aqueous layer is extracted with benzene. The benzene is evaporated under reduced pressure and the residue dissolved in a small volume of diethyl ether. This solution is poured into 200 m/ isopropanol. The mixture is kept in the refrigerator for 3 days. The yellow crystals of the bis[2-phenylethenyl] tellurium are separated from the red needles of the ditellurium compound, that melted at 82 (yield 6%). 

Tin(II) chloride (saturated). Shake 2-5 g tin(II) chloride dihydrate, SnCl2.2H20, in 5 ml concentrated hydrochloric acid. Allow the solid to settle and use the clear solution for the tests. 

The Step 2 product (4.55 g) was treated with tin (II) chloride dihydrate (18.0 g) dissolved in 100 ml of ethanol and 16 ml of lOM hydrochloric acid and then stirred at ambient temperature for 9 hours. The mixture was basified with chilled 20 wt% potassium hydroxide (160 g), extracted with diethyl ether, and purified by chromatography on silica gel the product was isolated as a light amber oil. 

Reduction of the nitro group of 6-nitroquinoxaline with tin(II) chloride dihydrate in ethanol yields the corresponding 6-amino compound in 71 % yield. ... 

The c/j-3-substituted-2-penten-4-ynal (262) predominantly formed by anionotropic rearrangement of 261 gave, on aldol condensation with methyl ketones, the diyne ketone 263. When a solution of the latter in THF was slowly added to a suspension of finely powdered potassium hydroxide in liquid ammonia, a mixture of the diastereomers of the cyclic glycol 264 was obtained. Treatment of 264 in benzene or ether with tin(ii) chloride dihydrate in concentrated hydrochloric acid gave the...
