Treatment of tridentate ligand with Ti(0 Pr)4 and di-ferf-butylsalicyclic acid (163) in toluene followed by evaporation of the solvent afforded an orange complex postulated to be 165, which was shown to be an effective catalyst for the Mukaiyama aldol reaction. Under optimized conditions, the simple methyl acetate-derived enol silane 166 adds to aldehydes in the presence of as little as...

Dissolve 0-2 g. of fructose in 10 ml. of water, add 0-6 g. of cw-methyl-phenylhydrazine and sufficient rectified spirit to give a clear solution. Since the fructose may not be quite pure, warm the mixture slightly, allow to stand, preferably overnight, so that any insoluble hydrazones may separate if present, remove them by filtration. Add 4 ml. of 50 per cent, acetic acid to the filtrate it will become yellow in colour. Heat the solution on a water bath for 5-10 minutes, and allow to stand in the dark until crystalUsation is complete it may be necessary to scratch the walls of the vessel to induce crystalUsation. Filter the crystals and wash with water, followed by a little ether. RecrystaUise the orange-coloured methylphenylosazone from benzene m.p. 152°. 

Bromoisatin [87-48-9] M 226.0, m 245°(dec), 251-153°, 255-256°. Forms red prisms or needles from EtOH. The N-acetate crystallises as yellow prisms from C6H6, m 170-172°, and the N-methyl derivative form orange-red needles from MeOH, m 172-173°.

It is interesting to note that the 7,12-dihydro-2-methyl-6H-indolo[2,3-n] quinolizinium chloride (216) (R = acetal) can be deprotonated to give the orange-yellow zwitterion 217, whereas the vinylog amide 218 is formed when R = COMe (Scheme 71). This substitution pattern gives rise to the... 

Dissolve 0.3 g of miconazole in 50 mL of a mixture of 1 volume of glacial acetic acid R and 7 volumes of methyl ethyl ketone R. Using 0.2 mL of naphthalbenzein solution R as indicator, titrate with 0.1 M perchloric acid until the color changes from orange-yellow to green. One milliliter of 0.1 M perchloric acid is equivalent to 41.61 mg of C18H14C14N20. 

The step 1 product (5.67 g) and 4-(2-ethylhexyloxy)-4 -formyltriphenylamine (5.20 g) were dissolved into 30 ml of THF and then treated with the dropwise addition of 28% sodium methylate (3.47 g) dissolved in methanol and then refluxed 1 hour and neutralized with acetic acid. The mixture was poured into water and extracted with toluene, washed with water, dried with MgS04, and concentrated. The residue was purified using silica gel chromatography with toluene/hexane, 1 2, respectively, and 5.60 g of product isolated as an orange-red glassy solid, mp = 93.0-93.5°C.

Pour 2-3 ml each of 1 iV solutions of hydrochloric and acetic acids, sodium hydroxide, and an aqueous ammonia solution into test tubes. Pour one or two drops of a phenolphthalein solution into each of the tubes and see whether the colour of the solution changes. Perform similar experiments with other indicators, namely, methyl red, litmus, methyl orange (see Appendix 1, Table 6). Enter your observations into your laboratory notebook using Form 14.
