Amines, reactions Amines are similar to ammonia in their reactions. Like ammonia, amines are basic. Like ammonia, amines are nucleophilic and react> NH
A novel one-pot practical approach for the preparation of isocyanide directly from amine and its reaction has been developed. It employs formylation of amine, dehydration of formamide to isocyanide, and its multicomponent reactions (Ugi, Passerini, and Groebke-Blackburn-Bienayme reactions). This meth...
Thus, the displacements of the bearing center are defined in the inertial coordinate system and include not only the radial displacements x,y and a xial displacement z but also the rotations about the x and y-axes,θx an 轴承的一般行动和装载可以在五个自由程度完全地被描述。 因此,轴承中心的...
(67,68) were obtained in 43 and 37% yield, respectively. It is worth noting the higher reactivity of the corresponding aziridinium intermediates in the case of propargylamines as the homodiaminated products were also formed and their separation was difficult, leading to relatively lower yields...
Since amides are readily prepared, their reduction is a favoured method for the making of all amine groups. Reductive Amination of Aldehydes and Ketones Catalytic or chemical reactions in the presence of ammonia or primary or secondary amines may eliminate aldehydes or ketones, resulting in primary,...
Ferri, Reaktionen der organischen Synthese (Reactions of Organic Synthesis), Georg Thieme Verlag, Stuttgart (1978) Chapter 1.3 or in Chapter 8. Isocyanates of the formula (III) can be obtained by a process in which dihydrooxazines, optionally in the form of acid adducts, are reacted with ...
For example, methods for preparing amines and their reactions are detailed in Sidgewick's "The Organic Chemistry of Nitrogen", Clarendon Press, Oxford, 1966; Noller's "Chemistry of Organic Compounds", Saunders, Philadelphia, 2nd Ed., 1957; and Kirk-Othmer's "Encyclopedia of Chemical ...
