Both racemic forms of trans 2-chlorodecalin have been prepared and separated in pure form. The reaction between these chlorodecalins and ethylmagnesium bromide has been studied and two racemates of trans 2-ethyl decalin have been isolated. Some progress has been made in the preparation of the 9-chlorodecalins. A new method for converting cis decalin to trans decalin rapidly in high yield using tertiary butyl chloride and anhydrous aluminum chloride is indicated.

Tert Butyl Chloride

A statistical model was developed for the alkylation of toluene with tert.-butyl chloride in presence of anhydrous aluminum chloride as catalyst. Temperature, molar ratio of toluene to tert.-butyl chloride and amount of anhydrous aluminum chloride were chosen for investigation. A set of trials was planned according to a 3 factor 2-level Yates pattern experimental design with 2 replicates and the center point trial with 4 replicates. The critical response was the yield of tert.-butyl toluene. Two- and three-factor interaction effects together with the main effects were statistically significant. The adequacy of the suggested model was checked up. The difference between the experimental and predicted yields did not exceed 2.22%. The best yield of the tert.-butyl toluene was 51.2%. Key words: tert. Butylation, Yates pattern, Experimental yield, Statistical model.     doi: 10.3329/bjsir.v43i4.2245 Bangladesh J. Sci. Ind. Res. 43(4), 545-552, 2008

General Method

In 1957, a new method for the synthesis of methylphosphonous dichloride, in high yield, by the reduction of the aluminum chloride – phosphorus trichloride – methyl chloride complex in diethyl phthalate solution by finely powdered antimony, was developed. That this is a general method for the synthesis of the more volatile alkylphosphonous dichlorides was demonstrated by the preparation, in good yield, of a series of compounds from the aluminum chloride – phosphorus trichloride complexes formed from ethyl chloride, n-propyl chloride, i-propyl chloride, n-butyl chloride, and s-butyl chloride. As expected, isomerization occurred in the case of the normal alkyl chlorides.
