A. l-Ethyl-3-(3-dimethylamino)propylcarbodiimide. A solution of 100 g. (1.41 moles) of ethyl isocyanate (Note 1) in 750 ml. of methylene chloride is prepared in a 5-1. three-necked flask equipped with a mechanical stirrer, an immersion thermometer, and a 500-ml., pressure-equalizing, addition funnel (Note 2). The flask and its contents are cooled to 5° in an ice bath, and a solution of 144 g. (1.41 moles) of N,N-dimethyl-l,3-propanedi-amine in 250 ml. of methylene chloride is added through the addition funnel at a rate such that the reaction temperature does not exceed 10° (Note 3). On completion of this addition 500 ml. of triethylamine is added to the flask, and a solution of 300 g. (1.6 moles) of -toluenesulfony 1 chloride in 300 ml. of methylene chloride is placed in the addition funnel and added to the reaction... 

The absolute configuration of vicinal diamines can also be determined from the exciton Cotton effects of their bis[A7-(5-bromosalicylidene)]191 or bis[y-aminoenone] derivatives. Thus, both A -(5-bromosalicylidene) 1 and A -[4-(3-penten-2-one)] 2 derivatives of (7 )-l, 2-propanedi-amine show negative exciton Cotton effects, characteristic of the least congested rotamer I.
