Solubilities of modified polymers were determined by placing about one mg of product in about three ml of liquid. These mixtures were allowed to stand at room temperature, with occasional agitation for one week. The following liquids were tested acetone, acetonitrile, bromobenzene, chlorobenzene, 2-chloro-propionic acid, diethyl sulfate, dimethyl sulfoxide, hexachloro-acetone, 5% LiCl/dimethyl sulfoxide, 5% LiCl/dimethylfuran, toluene and triethylphosphate. [Pg.208]

Irradiation of compound 357 (R = Me) in methanol and ethanol at 300 nm gave ethyl 2-methyl-4-oxo-4//-pyrimido[2,l-a]isoquinoline-3-car-boxylate (371) and 3-alkoxy-2-methyl 4//-pyrimido[2,l-a]isoquinoline-4-ones (369, R = Me, R1 = Me, Et) along with two imidazo[2,l-a]isoquino-lines (368, R = Me and 372) and a ring-opened product (92AJC1811). At 254 nm the yields of 4//-pyrimido[2,l-a]isoquinolin-4-ones (369, R = Me and 371) and 368, (R = Me) were lower no formation or trace of them was observed in acetonitrile, acetone, acetic acid, and ethyl acetate. Irradition of compound 357 (R = Me) at 300 nm in acetonitrile containing 36% hydrochloric acid afforded 3-chloro-2-methyl-4//-pyrimido[2,l-a]isoquinolin-4-one (373) in 31-81% yields and other products. [Pg.250]

To obtain more information on the nature of the quasiphosphonium intermediates involved in these systems we have studied the reactions gf sterically hindered neopentyl esters by means of 1P nmr spectroscopy. Trineopentyl phosphite and a-bromoacetophenone gave rise to a peak at +41 ppm due to the ketophosphonium intermediate 3 (R = Me.CCH, R = Ph X = Br ) within half an hour of mixingJthe reactants in acetone-dfi at 27 °C ( p nmr shifts are relative to 85% H-PO. down-field positive). Peaks due to the ketophospnonate 4 +19 ppm and the vinyl phosphate 7 (-7 ppm) were also observed (compound 4 and 7 have satisfactory elemental analysis and spectroscopic data ). The concentration of the intermediate reached a maximum after about two hours when it was precipitated from acetone solution by the addition of anhydrous ether to give white crystals of trineopentyloxy (phenacyl)phosphonium bromide, identified by elemental analysis and nmr spectroscopy ( XP 6+41, in CDCl ). When redissolved in acetone-dg, deuterochloroform, acetic acid, or acetic acid-acetone mixtures, the intermediate decomposed to yield keto-phosphonate 4 but none of the vinyl phosphate 6 (Perkow product). Nor was the course of reaction affected by the addition of chloride ion or of a-chloro-acetophenone in acetonitrile. [Pg.514]

The m-chloro-a-bromopropiophenone was dissolved in acetonitrile (1300 ml). To this, t-butylamine (733.0 g) in acetonitrile (1300 ml) was added while keeping the temperature below 32°C. The reaction mixture was allowed to stand over night. It was then partitioned between water (4200 ml) and ether (2700 ml). The aqueous layer was extracted with a further portion of ether (1300 ml). The combined ethereal layers were then washed with water (4200 ml) to which hydrochloric acid was added until the pH of the aqueous layer was 9. The aqueous layer was separated and washed with ether (500 ml) and then discarded. The combined ethereal layers were then stirred with ice (560.0 g) and concentrated hydrochloric acid (324 ml). The ethereal layer was separated and again washed with water (200 ml) and concentrated hydrochloric acid (50 ml). These last two acid layers were combined and concentrated in vacuum until crystals appeared. The solution was then chilled to 5°C and filtered. The product was sucked dry, washed with acetone and recrystallized from a mixture of isopropanol (3 L) and absolute ethanol (800 ml). The DL-m-chloro-a-t-butylaminopropiophenone hydrochloride so was obtained, melting point 233°-234°C. [Pg.733]

A 100-mg. (0.2-mmole) sample of ju-chloro-bis(cyclopenta-dienyliron dicarbonyl) tetrafluoroborate is dissolved in 2 ml. of acetone, and 0.5 ml. (10 mmoles) of acetonitrile is added to the dark red solution. The reaction mixture is heated to 20-30°C. for 1 hours. During that time the color changes to red-orange. Solvent and excess acetonitrile are removed under vacuum. The oily residue is treated with ether, and a yellow solid forms. The yellow solid is removed by filtration and is dissolved in 2 ml. of acetone. The solution is filtered then ether is added dropwise to the filtrate until no more precipitate separates. After the yellow crystalline product is dried under high vacuum, the yield is about 60%, based on [ CtH5Fe(CO)2 2Cl]BF4. Anal. Calcd. C, 29.78 H, 2.23 Fe, 15.39 N, 3.86. Found C, 29.86 H, 2.46 Fe, 15.47 N, 3.48. [Pg.42]

The diiodo compound is easily prepared from the commercially available 1,2-bis(2-chloro-ethoxylethane by reaction with anhydrous sodium iodide in dry acetone. b Acetonitrile may be dried by distillation from calcium hydride. [Pg.42]

Phenyl-4-methyl-7azaindole-3-carboxaldehyde (148, B = H, R = Ph Scheme 10) was reduced with sodium borohydride to the 3-hydroxymethyl compound (145, R = H, R = Ph) in quantitative yield,whereas the 6-chloro compound (145, R = C1, R = H) was obtained in only 10 % yield. Treatment of 145 (R = H, R =Ph) with thionyl chloride gave the 3-chloromethyl compound (146), isolated in 99 % yield as the hydrochloride. With sodium bicarbonate in water, the 3-chloromethyl salt (146) is hydrolyzed rapidly back to the hydroxymethyl compound (145). An attempt to synthesize the 3-acetonitrile (147) by heating the 3-chloromethyl salt (146) with sodium cyanide in ethanol produced only the bisazaindolylmethylene ether (50%). Use of acetone cyanohydrin gave the acetonitrile (147) (50 %). It was hydrolyzed to give l-phenyl-4-methyl-7-azaindole-... [Pg.73]

Complex 446 is a doubly chloro-bridged dimer in the solid state but is essentially monomeric in dichloromethane (or chloroform) solution (Scheme 101). Thus, coordination of an additional Lewis-basic solvent (S) molecule such as acetone, THF, and acetonitrile is feasible in a position tram to the Cp ligand to form a solvate, but no such stable solvates could be isolated. Methanol or water (X) displaces the ether side chain to form the bis(solvate) adducts however, the chelate is re-formed on removal of the solvent under vacuum to give stable methanol or water monoadducts. The THF-solvate of the water adduct has been structurally characterized. [Pg.849]

An even larger stereoselectivity has been found in the reaction of tetra-chloro-o-benzoquinone with trans- and m-stilbene under irradiation at 15°C ( > 400 nm) from iro/ii-stilbene in benzene, 88% trans product, and from cii-stilbene in acetone or acetonitrile 83% cis product are reported. A large measure of the steric control is thought to derive from the dipolar character of the intermediate . [Pg.117]
