(The energy of chloride is given at right.) Assuming that reaction (1) is normal , what is the effect of a benzene ring Does it facilitate or hinder loss of chloride ... 

A VEEL spectrum of the species formed by the decomposition of tert-butyl (2-methyl-2-propyl) chloride and bromide on Cu(100) at 185 and 120 K, respectively (193), shows intensity anomalies similar to those discussed for 2-propyl groups when interpreted in terms of surface terf-butyl groups. Further RAIRS and VEELS work is required.

To a suspension of 3.9 grams of potassium amide is slowly added a solution of 19.2 grams (0.1 mol) Of 5H-dibenzo[a,d] cycloheptene in 600 ml of ether with stirring. The suspension is refluxed with stirring for 3 hours, then cooled to room temperature and a solution of 0.1 mol of 3-(N-formyl-N-methyl)-aminopropyl chloride in 100 ml of ether added. The mixture is then refluxed with stirring for 5 hours and then 100 ml of water added. The ether layer is then washed with dilute hydrochloric acid, then water and then dried over magnesium sulfate and evaporated to dryness yielding 5-[3-(N-formyl-N-methyl)-amino-propyl] -5H-dibenzo[a,d] cycloheptene.

BINAP core-functionalized dendrimers were synthesized by Fan et al. (36), via condensation of Frechet s polybenzyl ether dendritic wedges to 5,5 -diamino-BINAP (26—28). The various generations of BINAP core-functionalized dendrimers were tested in the ruthenium-catalyzed asymmetric hydrogenation of 2-[p-(2-methyl-propyl)phenyl]acrylic acid in the presence of 80 bar H2 pressure and in a 1 1 (v/v) methanol/toluene mixture. As later generations of the in situ prepared cymeneruthe-nium chloride dendritic catalysts were used, higher activities were observed (TOF values were 6.5, 8.3, and 214 h respectively). Relative to those of the BINAP...

The combinatorial reactions chosen for the novel amines were amide bond formation and sulfonamide formation. The novel carboxylic acids were derivatized to simple amides. For the amine reactions, we chose two simple carboxylic acids (propionic acid and benzoic acid) and two simple sulfonyl chlorides (methyl-sulfonyl chloride and benzenesulfonyl chloride) as the capping groups. Propyl amine and benzylamine were chosen as the capping groups to react with the novel carboxylic acids. Because only one reactant will be variable, these combinatorial libraries were essentially 1 x N libraries, where the one reactant was a simple reactant and the N component is the novel amines or acids.

Hydroxy-3,4-dihydro-2H-pyrido[2,l-b][l,3]thiazin-5-ium chloride was formed when 2-hydroxy-3-(2-pyridylthio)propyl chloride was stirred in methylene chloride overnight (92JOC6335). When the reaction was carried out in methanolic sodium methylate, 3-(2-oxo-l,2-dihydro-l-pyridyl) thietane was obtained in 58% yield.

Methyl, propyl, butyl, etc., malonic esters are also obtained in a similar manner. It is to be observed that aryl halides do not undergo this reaction. The di-alkyl esters are obtained from the mono-alkyl esters in the same way as the latter are obtained from malonic ester. But although di-alkyl compounds are not formed directly in any quantity, yet it frequently happens that a little is obtained in the preparation of the mono-alkyl compound from 1 mol. of sodium ethoxide and 1 mol. of alkyl halide, owing to the mono-derivative reacting with more sodium and alkyl halide. This may be prevented when necessary by using only half the calculated quantity of sodium and alkyl halide. By this means the yield of benzoyl malonic ester for example is raised from 55% to 85% in its preparation from sodium, benzoyl chloride and malonic ester. (B., 44, 1507.)... 

In an exactly similar way acetone (B.P. 56°) can be prepared from acetoacetic ester (see p. 148) methyl propyl ketone (B.P. 102°) from monoethyl acetoacetic ester (see p. 140). The higher ketones may be purified by washing with saturated brine until alcohol is removed they are then, after drying over calcium chloride, fractionated. In all these hydrolyses dilute aqueous or alcoholic potash, or dilute sulphuric acid, may be used in place of baryta water. The yields in these preparations are all of the same order—70%.

Methyl magnesium chloride (3.0 Molar solution in THF, 790 mmol) was added dropwise over 30 min to the CeCI3 slurry at 0°C. After stirring 2 hours, the mixture was cooled to -5°C and a toluene (600 mL) solution of the ethyl 2-(3(S)-(3-(2-(7-chloro-2-quinolinyl)ethenyl)phenyl)-3-hydroxy-propyl)benzoate (152 mmol) was added dropwise over 1 hour. The reaction mixture was stirred another hour before the addition of 2 M HOAc (600 mL) and toluene (600 mL). The organic layer was washed with saturated aq. NaHC03 and with brine. Concentration in vacuo and purification of the residue by flash chromatography (30% EtOAc in toluene) gave 63.48 g (91%) of the 2-(2-(3(S)-(3-(2-(7-chloro-2-quinolinyl)ethenyl)phenyl)-3-hydroxypropyl)phenyl)-2-propanol.
