The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.4488-22-6, Name is [1,1′-Binaphthalene]-2,2′-diamine, molecular formula is C20H16N2. In a Article£¬once mentioned of 4488-22-6, SDS of cas: 4488-22-6
Dication C(R1)-N(R2)2 synthons and their use in the synthesis of formamidines, amidines, and alpha-aminonitriles
A combination of amides and 2-pyridinesulfonyl chloride was evaluated as synthons of the dication C(R1)-N(R2)2/2+. When the substrates were primary amines, high yields of formamidines and amidines were obtained. When the substrates were alpha-aminoamides, alpha-aminonitriles were obtained. Through this process, naturally occurring alpha-aminoacids can be transformed into chiral alpha-aminonitriles with complete retention of stereochemical configuration. All reactions proceed rapidly at room temperature, and normally finish within 10 min, with yields ranging from 80 to 95% for most cases. Among the sulfonyl chlorides examined, 2-pyridinesulfonyl chloride stands out in both reaction rate and selectivity of formamidine or amidine versus sulfonyl amide. The scope and limitations of the reaction among different types of amides as synthons and amines as substrates were examined. (C) 2000 Elsevier Science Ltd.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 4488-22-6, you can also check out more blogs about4488-22-6
