Ethoxyethyl benzene

A subsequent elimination of hydrogen halide prompted by the lability of halogen on the carbon attached to nitrogen, a second halogen addition, and a repetition of the cycle must account for the reported formation of 9-pentachloro- and 9-pentabromoethylcarbazoles on reaction with excess halogen in methanol and acetic acid, respectively. Addition of bromine to IV-vinylcarbazole in benzene as solvent was accompanied by 3,6-dibromi-nation in ethanol, 3,6-dibromo-9-(2-bromo-l-ethoxyethyl)carbazole was reportedly formed (cf. ref. 230).

Acetal-acetal interchange. Formaldehyde and acetaldehyde acetals can be prepared from methoxymethyl ethers and ethoxyethyl ethers, respectively, by reaction with TsOH in refluxing benzene. 

Addition of acyl anion equivalents (propenal d reagents) to ketones provides general access to a -hy-droxy enones. In an application of this method to pentaimulation, the trimethylsilyl- or ethoxyethyl-pro-tected cyanohydrins of a, -enals were used." The derived tertiary acetates undergo elimination (p-TsOH/benzene) to the divinyl ketones which cyclize in the acidic reaction medium (equation 25)." In some cases the a -hydroxy or a -silyloxy enones underwent cyclization but in much lower yields. Substitution in the ring and on the double bonds is compatible. 

The CuCli-CuO promoted hydrolysis is not solely limited to thioacetals—a variety of acetals are also deprotected [21]. Treatment of 26 with the copper catalysts in acetone-water afforded the spiroacetals 27 and 28 via concomitant hydrolysis of the thioacetal and benzylidene dioxy and ethoxyethyl acetals (Sch. 7) [22], Copper(II) chloride dihydrate has also been shown to hydrolyze a variety of acetals [23] and trityl groups can also be removed in the presence of copper sulfate in benzene to afford deprotected alcohols [24].

Tetraphenyltellurophene 1,4-Diiodotctraphcnyl-l, 3-butadiene is prepared by reaction of diphenylacetylene with lithium in diethyl ether and treatment of the resultant suspension with iodine. A 250 ml, three-necked flask is fitted with a reflux condenser, a stirrer, and a gas-inlet tube. The system is flushed with nitrogen, 1.5 g (11 mmol) of finely powdered lithium telluride, 2.0 g (3.3 mmol) of 1,4-diiodotetraphenyl-l, 3-butadiene, and 125 ml of 2-ethoxyethyl ethyl ether are placed in the flask. The mixture is stirred and heated under reflux for 8 h, cooled, and poured into 1000 ml of water. The organic layer is separated, the aqueous phase is extracted with benzene, and the combined organic phases are dried with magnesium sulfate. The organic layer is filtered, the filtrate is evaporated, and the residue is recrystallized from dichloromethane/ethanol (charcoal) yield 1.3 g (82%) m.p. 239 .

To a resin kettle equipped with a mechanical stirrer and dropping funnel is added a solution of 64.3 gm (0.5 mole) of /7-chlorophenol, 15.0 gm (0.5 mole of formaldehyde) of 5-trioxane, and 1.0 gm of p-toluenesulfonic acid monohydrate in 30 ml of 6/5(2-ethoxyethyl) ether. The solution is heated under reflux at 110°C for 3 hr. At this time 100 ml of benzene is added and... 

Materials. PCPP was synthesized from soluble poly(dichlorophosphazene), (PNCl2)n, which was prepared by the thermal ring opening of hexachlorocyclo-triphosphazene, N3P3CI6 (9). The poly(dichlorophosphazene) dissolved in benzene solution was reacted with the sodium salt of p-chlorophenoxide, which was prepared by reaction of sodium and p-chlorophenol in a 2-ethoxyethyl ether / 1,4-dioxane cosolvent system, to form a fully substituted homopolymer, [PN(OC6H5Cl)2]n, PCPP, as reported by Reynard et al.(27). The product, PCPP, was then isolated and purified...
