Small quantities of the sjunmetrical ketones (CHjjjCO and (CHjCHjCHjjjCO (di-n-propyl ketone) are formed as by-products these can easily be removed by fractional distillation through an efficient column. An excess of the cheaper reagent, acetic acid, is employed the resulting acetone is readily removed by washing with water and little di-n-propyl ketone is formed under these conditions.

Aza-3,4-benzo-5,6-dipropylpentatriafu]valene hydriodide (373) was obtained in 20% yield by the action of l,2-di-n-propyl-3-ethoxy-cyclopropenium fluoroborate on indole magnesium iodide in a methylene chloride-ether mixture.

Molecular weight determinations have been carried out with methyl-ethyl-, diethyl-, di-n-propyl-, pentamethylene-, and methylphenyl-diazirine. They gave monomeric molecular weights. The three last-named compounds gave the calculated C, H, and N values by the usual procedure of microanalysis. 

Preparation of Di-n-Propyl Acetyl Tropine Hydrochloride Tropine (11.12 grams) was dissolved in 100 ml of anhydrous pyridine and to this solution was added 15.64 grams of din-propyl acetyl chloride. The mixture was refluxed for 6 hours. This solution was then cooled and the pyridine removed in vacuo. The residue was dissolved in chloroform. The chloroform solution was washed with 10% hydrochloric acid to remove the residual trace of pyridine. The hydrochloride of the product ester is soluble in chloroform and is not extracted from chloroform by hydrochloric acid. This is an unexpected property.
