The rates of the reaction of a series of alkyl-substituted cyclohexyldimethylamines and trans- decalyldimethylamines with methyl iodide in methyl cyanide and 98% methanol have been determined. Considerable scatter was found for the rates of the" equatorial" as well the" axial" 3-and 4-alky1cyclohexyldimethylamines.'{he rate of the 9-methyl-trans-decalyl-2~- dimethyl amine exhibits a notable acceleration relative to trans-decalyl-2~-dimethylamine. ...
