Cool the flask in ice, acidify with 10 ml. of cold 1 1-hydro-chloric acid and distil under reduced pressure (water pump) until most of the alcohol is removed. Add water to the residue, extract several times with ether, wash the combined ethereal extracts with N ammonia solution until a test portion gives no precipitate upon acidification. Extract the combined alkahne solutions once with a fresh portion of ether, and add the aqueous solution to an excess of dilute hydrochloric acid the final mixture should still be acidic to Congo red. Collect the crystalhne half-ester by filtration at the pump, wash it with water and dry at 100°. The yield is 14-5 g., m.p. 122-125°. Recrystallise by dissolving in about 40 ml. of warm benzene and adding an equal volume of petroleum ether (b.p. 40- 60°) 13 -5 g. of the colourless half-ester, m.p. 125-126°, are obtained. 

Hydrazobenzene (9-2 g.) dissolved in the minimum quantity of ether is added drop by drop with shaking to 100 c.c. of ice-cold, approximately 7 N-hydrochloric acid (concentrated acid diluted with an equal volume of water). Crystalline benzidine hydrochloride separates and, after 50 c.c. of concentrated hydrochloric acid have been added and the mixture has stood for half an hour, the hydrochloride is filtered at the pump, and washed, first with 7 N-hydro-chloric acid and then with a little ether. Yield 9-10 g. The hydrochloride can be recrystallised by dissolution in hot water and addition of concentrated hydrochloric acid to the slightly cooled solution. 

To a solution of 3 (8.7 g, 0.06 mol) in anhydrous pyridine (150 mL) lS-camphanic chloric (18.7 g, 0.086 mol) [48] was added and the mixture was left at room temperature. After 48 the solution was poured into ice-water and extracted with CHC13. Combined chlorofor extracts were washed with water, dried (MgS04), and concentrated to dryness. Crude est was dissolved in 40 mL ether and cooled to a — 15°C. The deposited crystals (first fractio 8.96 g) were crystallized four times from the same solvent, 4.5 g of pure 3 mp 102 103.5°C, [a]578 - 29.8° (c 2.02, C6H6). 

Wang et al. reported the self-assembly of organometallic linear-dendritic polymers containing ferrocenyldimethylsilane.357 The linear polymers were prepared via the anionic ringopening of [l]si aferrocenophane, followed by the addition of dendritic chloric poly(benzyl ether). Self-assembly of the polymers was examined in acetone and was reported to occur at concentrations of 0.18 wt %, with a spherical diameter of 50-150 nm. At higher concentrations (0.35 wt %), a bilayer with core spheres formed and at (0.7 wt %) bilayers spheres were formed. 

Piperonyl alcohol 328 2-Propanol is rendered anhydrous by 4 hours boiling with calcium oxide, distillation, further boiling with aluminum isopropoxide, and renewed distillation. 50 g of piperonal in 500 ml of this alcohol are treated with 10 g of aluminum isopropoxide, and the whole is heated in an oil-bath at 95° under a Widmer column attached to a descending condenser. At the end of this time, 200 ml of distillate have passed over (b.p. 77-81°) and acetone is no longer detectable in a sample by means of 2,4-dinitrophenylhydrazine in N-hydro-chloric acid. The residue is treated with water, made just acid with hydrochloric acid, and extracted with ether. The extract is dried and evaporated, and the residue is distilled in a vacuum, giving 45 g of a product of b.p. 151°/13 mm. This solidifies to crystals melting at 51°. 

Dissolve 1 g. of the secondary amine in 3-5 ml. of dilute hydrochlorio acid or of alcohol (in the latter case, add 1 ml. of concentrated hydro chloric acid). Cool to about 5° and add 4-5 ml. of 10 per cent, sodium nitrite solution, and allow to stand for 5 minutes. Add 10 ml. of water, transfer to a small separatory funnel and extract the oil with about 20 ml. of ether. Wash the ethereal extract successively with water, dilute sodium hydroxide solution and water. Remove the ether on a previously warmed water bath no flames should be present in the vicinity. Apply Liebermann s nitroso reaction to the residual oil or solid thus. Place 1 drop or 0 01-0-02 g. of the nitroso compound in a dry test-tube, add 0- 05 g. of phenol and warm together for 20 seconds cool, and add 1 ml. of concentrated sulphuric acid. An intense green (or greenish-blue) colouration will be developed, which changes to pale red upon pouring into 30-50 ml. of cold water the colour becomes deep blue or green upon adding excess of sodium hydroxide solution.
